Aspose.Cells 25.11 - Refreshing XLSM Pivot Tables corrupts the file

Aspose.Cells Product Family

Hi,

I’m using Aspose.Cells 25.11 for .NET, and during our calculation engine we run refresh Pivot Tables.

When using it on .xlsm file it returns a corrupt workbook and changes the order of some columns on the workbook.

The process doesn’t throw an exception, simply returns a corrupted workbook.

Attached is a small program reproducing the issue.
