we have an excel spreadsheet saved in our shared drive.  when two people work on it & both people save the version that he/she is working on, a second version with one of their email addresses at the end of the document name is saved.  (see below.)  does anyone know how to prevent this from happening?  or do we just have to delete that second version immediately every time it's generated?  (we can't leave it in the shared drive because it causes confusion.)  thanks.
