I'm doing a lot of back and forth between Noteworthy Composer on my PC and MobileSheets on my Azpen in order to load, update and reload my songs.  This seems to be the reason why I end up getting a lot of duplicates and even triplicates of songs in the songs tab.  I don't understand why this should happen given that a window pops up with the default as overwriting the previous file. 

I think I can avoid this problem by deleting a song before I reload an updated version, but I don't always remember to do this.  The problem is that I can't delete extraneous copies without losing them from their set lists.  Is there a way I can overwrite an earlier version of a song so I don't have this problem?

Thanks
