Document corruption on specific document


I have a document in *.xls format which can be opened by Microsoft Excel without any problem.
When I resave the document by Aspose.Cells and try to open it by Microsoft Excel, I have a message that the document is corrupted.

I resave the document with such type of code:
Workbook wb = new Workbook(fName);
wb.Save(nFName, SaveFormat.Excel97To2003);

The issue seems to be in a comment, if I delete it, the document will not be corrupted.
I attached an original version of the document (F3D477823295.xls) and corrupted version (F3D477823295.xls.xls).
aspose.zip (21.8 KB)

I use Excel 2016 and Aspose.Cells v17.9.0.0.

Best regards,
Alex Shloma
