Hello, Aspose team!

Thank You for all your hard work for fixing issues in your product!

I have another issue in Aspose.Cells.
In the attached sample project you will find intial file called "test_template.xlsm"

All that this sample project do is just workbook open from file - workbook save into new file.

But afterwards file become corrupted (see the big grey line appearing in the file out.xlsm in the bin folder)
