Pokemon textures won't replace, trainers do though

I did a search for the answer, but only found people having problems with freezing.

How it's hacked:
___________________________
Ash | SquitleSquad | Bulbasaur | (charizard not replaced)
Gary | Totodile | Bayleef | Typloshon

How it loads:
Ash | Squirtle | Ivysaur | Charizard
Gary | Squirtle | Ivysaur | Charizard


I don't get it.
