Deleting sheets not working correctly

[KaareKristensen]

Description
I have some code that opens a file and deletes all sheets apart from a single sheet. The code then creates more sheets and populates them with data using file.SetCellValue. If the code created the file itself it does not work, if I created the file and the code then edits it then it does work.
The problem is that when I open the file in Excel I get an error and Excel tries to repair the file. The inserted data is gone after the repair.

Steps to reproduce the issue:
temp.zip

1. Run the included code to create a file
2. Run the code again to "edit" the file, although it just sets the same values in all cells
3. Open the edited file in excel

Describe the results you received:
Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.
Replaced Part: /xl/worksheets/sheet2.xml part with XML error. Declared prefix. Line 2, column 143.
Replaced Part: /xl/worksheets/sheet3.xml part with XML error. Declared prefix. Line 2, column 143.

Note that I have not created a sheet by these names.

Describe the results you expected:
I expected to see the new sheets with the new data and no error message.
