Defect workbook with 17.3.X- but not with 17.2.X


It seems, Aspose Cells .Net destroys buttons -> Excel says workbook has a problem:

Following code run with 17.2.X loads and saves workbook normally, 17.3.X (even 17.3.10) destroys it:

private static void Test_ResaveWorkbookButtonProblem()
string srcFilePath = @“C:\temp\DataTest\AsposeTest\LoadAndSaveWorkbook\SrcBook.xlsm”;
string tgtFilePath = @“C:\temp\DataTest\AsposeTest\LoadAndSaveWorkbook\TgtBook.xlsm”;
Workbook wbSource = new Workbook(srcFilePath);

It may have to do with the button or the connection to a macro:

“Code anzeigen” means View code.

I am using .Net 4.0 version.
Let me know if you need some further information.
