Pokemon White - Zorua shows up as Choroneko?

Someone I know breeded a Zorua for me and traded it to me. I just got in a battle and it says "What will Zorua do?" and all, but the name of the pokemon, as well as the sprite, is a Choroneko (USA: Purrloin).Is this because I am using a rom on my M3 DS Simply? I am a bit bummed by this. :<Edit:I forgot to mention, this is a JP rom with the English patch.

its zorua ability 'illiusion' it makes the name and sprite that one of the last pokemon you currently have with you

Oh, hell. Good to know then. Scared the crap out of me for a good few minutes. I've been making it a point not to "cheat" on my rom. Only got it because I'm a cheap mofo. Didn't want people to be all "wtf" on me.Thanks for the info!
