Hey! I'm one of the people who brought up being confused about this and actually, I think this might have been the case for at least some of them? Because I looked again and I noticed that, to quote my own post:
[...]
None of this is correct anymore! Reneigh is now listed as uchi A, and it's the uchi B section that only has 4 villagers under it. When I go and look at the FreeA_AlwaysA section, it does have the dialogue I've gotten from Reneigh. Punchy and Chief are also now listed as lazy B and cranky B respectively. I also checked my other villagers and I'm not sure about my smug, peppy, or normals as I don't know if I've ever gotten the subtype-specific dialogue from them at all, but all the others seem to match! So yep, I think there was just a mixup somewhere as you suspected.
