Duplicate option doesn't work
- The function Duplicate for workbooks doesn't work properly.
- If the workbook has been created on the New site, by duplicating you get a new empty workbook.
- If the workbook comes from the Old site, by duplicating you get a new workbook with 2 (always the same) worksheets you've never added to any workbook.
