We met a problem when operating aspose.cell

Hello,
Now our client met a problem when operating aspose.cell, can you help us to solve this problem?
When they use the official version and try to add the watermark & QR code into an excel files, then set it can't be edited. After that, they click the "Print preview" , but the excel crashed.
They test the trail version with same operation. But it works fine.
And we can show you two files to confirm.

Thanks & Regards

Hi,


We noticed the issue with your attached “(Add_watermark)test.xlsx” file when viewing it in MS Excel Print Preview.

Could you try our latest version/fix: Aspose.Cells for Java v8.1.2.5 if it makes any difference.

If you still find the issue, kindly do create a sample JAVA program (runnable) and post us here to reproduce the issue on our end, we will check it soon.

Thank you.
