Customer claims our PDF is corrupt

We render PDFs from XPS with Aspose.Pdf.dll version and haven't had a problem with them being ingesting by third party content systems. However, one customer is reporting that the files are corrupt even though they load fine in Adobe Reader.

We used the following tool to validate the PDF:

and got the following error:

It was a decompression error “stream # 6 org sz = (0x41)”

Once the PDF generated by Aspose is repaired, the customer's third party system can accept it. Why would Aspose generate a PDF that is considered corrupt and departing from the Adobe standard?
