Go to Settings->Library Settings->Tab Selection and Order, add the Source Types to the left list, go back to the library screen, go to the Source Types tab, then long press an entry to select it, tap each one you want to delete, then tap "Delete" at the top of the screen to delete the duplicate entries. If you enable Settings->Library Settings->Show Number of Songs, you can see how many songs are present in each entry before deleting it.
