PDF export from Writer w Timestamp from TSA shown as "Modified" in Acrobat Reader

Hi,

While having configured the correct Non-repudiation certificate from eID and TSA timestamp, LibreOffice Writer export to PDF results in PDF document detected as “Modified”; that is - possible forgery.

Acrobat Reader’s “digitally sign” doesn’t have this bug.

Is there a way to do a clean export, bypassing proprietary technology and software?

Thank you,
mt

Writer signature 'Modified'

P.S.

This happens even after immediately saving the .ODT original.

I’m afraid, Libreswan is unrelated to LibreOffice project.

If you use LibreOffice, it would be nice if you mentioned the information from HelpAbout.

OMG, I was all in Libreswan last week, so probably hence the blunder.

Yes, it is the LibreOffice Writer, of course.

Here is the Help → About output:
