The conversion from PDF to PDF/A has some problem.
The situation is as follows, when digitally signing a PDF and then convert to PDF/A using Aspose and if you make at least two digital signatures, with save between them, the first signature becames invalid after the second.
If I repeat the same process but using a PDF/A taken from another program(just open and save), both signatures are still valid after.
