Hello,

Thanks for your feedback.
I simulated a document and tested it using the latest version of Spire.Office, but I did not reproduce your problem, you can test my provided testing document. Your issue should be related to your document data. Thus we still need your file to facilitate our further investigation. Don’t worry, we promise to keep your documents confidential and won’t use them for any other purpose, also you could remove the security data of your document and then send it to me via email (simple.li@e-iceblue.com).Thank you for your understanding.

Sincerely,
Simple
