If you enable "Add Unique Id to Filenames", it modifies the filenames to ensure you never have file conflicts. Unfortunately, that also means that MobileSheetsPro won't correctly detect when you are attempting to import a file to update an existing song. The only way to update your song at that point is to long press the song, tap the overflow menu at the top right and then select "Swap File". You can then swap in the file without the unique identifier in it. I have been considering lately completely removing the "Add Unique Id to Filenames" option, as I don't think it's necessary any longer, and was only left in place to ensure compatibility with the original MobileSheets. At this point, it just causes headaches for users who don't realize the implications of enabling that setting, and provides little benefit as MobileSheets asks for files to be renamed when conflicts occur anyways.

So you don't have to erase your library, but you will have to use the "Swap File" feature to update your songs instead of being able to just reimport those files.
