Yeah, Adobe claims that the stamp annotation was modified.
despite that it wasn't. The stamp annotation is object "40 0 obj" and
that one exists only once at offset 58158 (related objects 41-45 also
exist only once). So I'd say Adobe is lying.
However... this may be a coincidence, but your signature is an invisible
one, so maybe the problem is related to this (fixed) bug?

When I open these files in the acrobat reader, I click on Validate ALL
in the Signature panel, I get a warning on the annotation that says
"modified annotation".
