Hi jcharneski2001,
Thanks for your response.
If you are using older version of Spire.PDFViewer, we first suggest upgrading to the latest
Spire.PDFViewer Pack Version:2.10.
After trying this version, if the issue still exists, I am afraid that the only way to fix this issue is providing us sample document via email, as different document maybe has different reason caused this issue. And we will appreciate if you can provide us the sample file, and promise to keep it confidential.
Sincerely,
Betsy
