The names of players on FIFA 11 are...not right?

I don't know what caused it or how to fix it but all the names are messed up. When I play Ultimate Team the names are right. But mainly when I play Head-to-Head or online using real clubs. For example: Ronaldo is Crofts, Gonzalo Higuian is Ho Young, Messi is Michina, Xabi Alonso is Yapi Yapo. I don't understand why it does this. Just all of a sudden it did this. (It happened a long time ago but I never got around to posting an question for it.)
