I would need to add a new feature to explicitly remove duplicates from a setlist, because users often do add the same song multipe times to a setlist which is a perfectly valid thing to do. One thing I might suggest if you need an immediate workaround is to add your setlists to a collection first, which won't allow duplicates, then you can just convert that collection to a setlist. It does require a few extra steps, but it would eliminate you having to remove the duplicates.
