PDF to PDF/A1 generates a file not passing Adobe Preflight

Hello,
we are using Aspose.PDF release 22.7.1 running with Java JDK17 and found an issue when converting a PDF to PDF/A1A. The ‘convert’ method returns true but the generated document fails validation in Adobe Acrobat Pro XI preflight check.
Attached you can find the testing Java code and the screenshots of the generated log.xml and Adobe PF checks.
In Aspose.PDF documentation is mentioned that you follow the Adobe PF checks specification, but it this case they fail even if the conversion is reported to be ok by Aspose.PDF. The output log xml is also not reporting the same issues found by Adobe PF checks.
Are we doing something wrong?
Many thanks in advance for your support.samplePdftoPdfA.zip (716.7 KB)
