Hello,
we suffer from the same issue in PD4ML 3.9.5. We try to merge two or more PDF files both/all created with PD4ML. It seems that this issue was introduced in PD4ML 3.9.4 or 3.9.5. With PD4ML 3.9.3 it works. I didn’t try 3.9.4 because in the release notes you mentioned changes in PDF merge logic. So I suppose version 3.9.4 is also corrupted.
Kind regards,
Norman Seidel
This is what PD4ML logs in debug mode:
