OS: MacOS Sonoma 14.0

Hi there! Thanks for this wonderful library. Our project involves filling fillable PDFs using this package and I've run into an issue with one of the PDFs. It's giving the following error when I run pdfcpu validate:

validation error (obj#:864): pdfcpu: array element 0 not a number (Float/Integer

The package works wonderfully with the other PDFs, so I think it's a problem with this particular file, but I have no clue what it means or what array it's referring to in order to fix it. Any help would be greatly appreciated!

Also, I noticed that this error was posted in this issue from 2 years ago (error number 6 in #384 ), but I can't find the follow ups with any solutions, so if there is something that you can point me towards, that would also be greatly appreciated.

Thank you! ^^
