if you process Clear comments from attached excel … than save the workbook in different name, you can reproduce this. We believe the arrow on the attached workbook sheet is the one cause the issue.
public void ClearAllWorkbookComments()
foreach (var sheet in _workbook.Worksheets)
Can you please let us know if you need more information.
