NullReferenceException when saving particular XLSM to XLS

Hi Aspose,

We are having troubles with this file. We can convert it from .xls to .xlsm. But we are getting NullReferenceException when saving this .xlsm back to .xls.
This file contains Vba code and shape that is bind to some macro. Unfortunately, we do not have password to Vba project, but hope you do not need it to troubleshoot.

@licenses,
I have tried the scenario using the following sample code with the latest version Aspose.Cells for .NET 20.2 but could not observe any issue. Could you please share your sample code to test this issue.

Workbook workbook = new Workbook("Sample.xls");
workbook.Save("Output1.xlsm");
Workbook workbook1 = new Workbook("Output1.xlsm");
workbook1.Save("output2.xls");
