I’ve never used Setlist.fm and don’t know how their algorithm works, but in our usage those two versions are actually different recordings (they would likely be the same work, but those are used so much less than recordings). Indeed, if you look at what we have in the database, the live version is correctly separated from the one on the album. If Setlist.fm only displays the tracks on the live album, there’s not much we can do here – they could be given more data (and a linking work in particular), but they are still technically correct as far as our own guidelines go, and any improvements made won’t do much for other services. You’re going to have to ask over there to get it fixed. Sorry!
