This is not a bug in UEFITool, that is a bug in image organization.
05CA01FC-0FC1-11DC-9011-00173153EBA8 is a GUID of AmiRomHole0 file, and it's located at a fixed address in the image, but there's no indication about that anywhere: it's not even aligned (FFS File Attributes are 0x00).
What's wrong here is the following: pad files used to align AmiRomHole0 and AmiRomHole1 shouldn't be pad files at all (so they won't be removed by reconstruction).
Please create an issue on GitHub about adding support for AMI ROM holes, maintainers will try to do something about that.

THANKS fernando for the nice and easy quide !!

@Fernando @CodeRush - I am not good at writing out bug reports And this is not specific to any one BIOS, I see this often in many different BIOS, never a specific brand or board series/BIOS type.
Usually when I see if if 25.1 destroys the padding, using 25.0 wont, that is the usual fix 98% of the time (Rare to have to use MMTool) However, this BIOS we looked at in this instance, what CodeRush mention surely applies since he checked out the specifics.
Surely that isn't the reason for the paddings every time I've run into the issue, since it's different manufacturers coding the BIOS each time?

I see this maybe once or twice every few weeks, varying BIOS brands/ board series, OEM and mainstream.
I could try and maintain a list of BIOS I see this with, to update to someone once a month or something, or add to the bug report maybe if someone can make one (I've never used gitbub except to download)

Hello!!! Big thank you for your help !!!!! This is the only foreign resource where I found a solution to my problem!!!

@Fernando:
What step you used when flashed on P8z77 v Deluxe, i used with bios flashback but not successed, i used 1 usb fd and mmc with adapter, but not successed, can you have me some advice
Thanks

HELP
Could you please verify if i have done the NVME insertion correct. I have an Asrock Z77pro4-M motherboard. I could not locate the text 'pci bus lane' in the file. Thanks in advance.

Thanks for your feedback

@Lost_N_BIOS:
Thank you so much for the instructions Lost_N_BIOS. The way my vision is these days I would not have been able to sort out the correct procedure myself.

The BIOS flash was a success - I still have a functioning computer, not an oversize novelty doorstop. When executing the BIOS flash command (fptw -bios -rewrite -f ), FPTW began by showing a message in Yellow "PDR Region does not exist". But as it immediately began to erase the BIOS there was no option other than to let it continue. Fortunately it concluded successfully and my computer rebooted without any problems.

I don't have a spare NVME SSD to test it yet. (Amazon's cost cutting seems to have gone too far and they usually neglect to seal the ends of their 'book mailer' type packaging with tape, leaving a gap large enough for a small item to fall out. As a result I received an empty package without my M.2 SSD.) So I dumped the newly flashed BIOS again and confirmed that the NVME module was present.

[Edit]
Do the 0x8A & 0x8B variables revert to their original state automatically, or should they be reset manually to protect the BIOS?

EDIT by Fernando: Unneeded fully quoted post replaced by directly addressing (to save space)

@davelister - glad all is well and your board is updated BIOS and running now! no PDR region is normal. You did the mod again with a backup first correct? Hope so!

That's bad about your SSD, I bet someone stole it on purpose rather than it slipping out, hopefully Amazon comes through for you on a replacement without hassles!
You can reset those variables, or leave them unlocked, it's Ok to leave if you want, I doubt any Virus being made for unlocked BIOS now that would end up on your system without someone physically accessing it in person.

Yep, I was very careful to backup my BIOS first (dump at least twice, then compare hashes & load into UEFI Tool just to make sure it's not garbage). Losing serial numbers & MAC addresses would have been bad - definitely worth a warning in big red letters.

Regarding the SSD, it happened a couple of months ago and Amazon have been worse than useless. (Wouldn't respond to anything I wrote in an email - not even a request that they confirm if my messages were being read by a human. Just kept sending the same long standard text over and over. Highly insulting.) Fortunately there are a couple of legal avenues available to consumers here in the UK. The Small Claims Court is one option. But an easier route is to go to your bank. If you used credit (including credit cards) for purchases (or part of) over £100 then the credit provider has joint liability, under section 75 the good old Consumer Credit Act 1974. (Another option for debit cards & lesser amounts are Visa's own Chargeback rules, but they are Visa's own rules not a legal right.)

Sent a dossier of evidence to my bank last month. Haven't heard back yet, but noticed the other day that the money has been credited back to my account.

Moral of the story? Don't waste time trying to reason with idiots! Ask nicely once, then hit them with a big stick.

Have a Merry Christmas and may 2019 be better than 2018.
