there is only one ComboBox in a new template workbook. Nothing another.

When result file is creating from template, only number 1 is writing to cell A1 by XLSRW.
Just presence of object ComboBox is enough to cause corruption in result file.
During openning the result file excel shows error message "corrupted file repair/cancel" with opening the result file.
If I choose "repair" then CoboBox is deleted by excel repair.
If I use a template without object ComboBox, the result file is ok.
I tested it with XLSRW 5.20.46
Important note - it depends on version of Excel
So if I make or save the template under Excel 2013, 2010 the result file is corupted.
If I make or save the template under Excel 2007 everything is OK


(If I make the template under Excel 2013 and after that I open and save it under Excel 2007 the result is ok too.
