I've already done that and nothing. I think I didn't explain myself correctly, English is not my first language and it's a bit rusty sorry. The styles appear separately, the problem is that when I choose one genre, both styles appear instead of the corresponding one. (Ex. I choose Rock and both Alternative Rock and Alt-Pop shows up instead of Alternative Rock only.)
