I've seen this previously & wonder if those alts are actually the Parts 1 & 2 from the 10" LP ie the alt is part 2 for the LP - just a guess, otherwise the 10" would be a very short (EP size) recording - the 10" LP actually has 7 tracks according to an online sale description
Here's another version of this session
