The nesting of "Star Wars - All Media Types" is, as usual, creating a mess :p
group: Cassian Andor/K-2SO -- in Rogue One Group: Cassian Andor/K-2SO (Star Wars) -- in SW:AMT. I would probably leave the Rogue One tag and delete AMT.
L3-37 (Star Wars) - appears under SW:AMT and Solo L3-37 (Solo) - appears under Solo. I would probably keep under Solo only.
Fennec Shand -- appears (without disambig) in SW:AMT, The Mandalorian, and The Book of Boba Fett Fennec Shand (The Mandalorian) -- appears in The Mandalorian I don't know where this character actually belongs.
Group: Din Djarin/IG-11 (The Mandalorian TV) Group: Din Djarin/IG-11 (The Mandalorian) both appear in the correct subfandom, but only one is needed
Some other characters like Chopper and AP-5 I suspect are double-tagged and showing up in AMT as well as elsewhere, but I don't know where they actually belong. I'm not sure if there's any tag that is better in AMT than elsewhere--like, I could see someone wanting C-3PO/R2-D2 across all the trilogy eras, not in one particular subfandom, but I'm not sure if they're there on purpose or because Ao3 is a mess.
