Aspose corrupts document when re-saving it to *.xls format

Aspose.Cells Product Family

Hi Aspose team,
Recently we faced with the issue when Aspose.Cells.dll corrupts document when re-saving it to *.xls format.
Microsoft Excel is able to open the document, but it blocks editing and shows a warning - “PROTECTED VIEW Office has detected a problem with this file. Editing it may harm your computer.”.
The issue is with a chart title. The issue disappears When the title is set invisible.
Code sample to reproduce:

Workbook wb = new Workbook(fName); 
wb.Save(nFName, SaveFormat.Excel97To2003);

Reproduced with:
Aspose.Cells 19.4.0.0
Microsoft Excel for Office 365 MSO (16.0.10730.20264) 32 bit

Added the documents with the chart alone (Test2.zip (12.9 KB))

  • test.xls - the original document;
  • test.xls.xls - corrupted document.

Please help with this problem.
