Hello,

Thanks for your post. After an initial test with Spire.XLS Pack(Hotfix) Version:8.4.6, I was unable to reproduce the issue. Please use the version and try again. If you still encounter the issue, please share us with your Excel file and full code for further investigation.

Best regards,
Simon
