Friend suggestions playing up

My friend suggestion buttons (add friend & remove from list) are misbehaving somewhat. When I click on either add or remove a suggested profile, it moves the profile either up or down or somewhere else in the list, but it doesn't add or remove them.

I think it is since you changed the icons on the buttons, but don't quote me.

I'm using firefox 13.0.1 and also get the problem in Chrome 19.0.1084.56 m.

I haven't tried ticking the box and following them all, as some of them are undesirables.
