List Bug

I made a list of Musicians and a list of Actors, and neither will let me remove or rearrange the list. I accidentally put a United fan under a list of Spurs fans and I want rid of him, but it keeps just refreshing with him still there.

Thanks, I find it so much better having that x to click when deleting things from the list! Had a bit of trouble moving things around on there too, not sure if it was me being a fool but when I was dragging items across it was opening them and making me have to click back and start again.
