festin: TrainerFu probably isn't smart enough to figure out that you aren't eligible to learn that stuff. As Kaerus mentioned, I think there may be a way to remove stuff from the list, but I'm not sure off the top of my head what that is.
TrainerFu is no longer being maintained as far as I can tell, so I don't expect any improvements to be made beyond locale translations.
This looks like plague. First Trainerskills now this.
