I see several duplicates here - Sevyn, Nomar, Myron, Miyu, etc.
It seems not a problem with this page though, but a consequence of there being duplicates in the CharacterMisc Cargo table, like the 2 entries for Sevyn look to me to be identical except one has a JP release date while the other lacks it.
I don't see why this has occurred - there is only 1 #cargo_store in Template:CharacterMisc that builds it so...I dunno, perhaps this cargo table needs to be rebuilt? Which I don't have permissions for so I'll leave it your hands, but I saw something so I thought I'd say something in case it helps!:-)
