Okay, I have Oblivion and Shivering Isles both installed onto my computer.
However, only recently when I have tried to update my game with patchs.
After installing these patchs, I went immediately to character creation and noticed that three of my original non-custom races have weird fonts for the name of their race and the description of their race.

How can I fix it? It's quite bothersome, especially when having friends that have never played that would like to try come over and are interested in the animorphic-races.

Get the construction set.

Go to files - data, then check your plugins. Go under characters, find races and see if there is anything wrong with the names and descriptions.

It probably won't work though :O. You might need to reinstall.
