Dear shony,

Thanks for your inquiry.
If you are using older version of Spire.XLS, we first suggest upgrading to the latest Spire.XLS Pack Hotfix Version:7.12.11. Hope this helps. If the problem persists after trying, please upload your sample document and the code you were using here, or send it to us(Support@e-iceblue.com) via email. That would be helpful to investigate this issue.

Thanks,
Betsy
