Info.pac acting weird

[Jugy3]

For some reason when i try to replace a character name or mark in info.pac the battle portrait, the lives and name have weird colors and are all glitchy. I'm trying to replace donkey kong's name with shadow, but yeah that's what happens.
Everything was fine before i downloaded this stage expansion hack:

Maybe there's some kind of glitch? I dunno :/
