Friend List Messing Up

I'm not sure what could have caused this. I opted in the Find friends by social network. And that's all I think I could have done with the Friend list.

"Show offline friends" is unchecked but the offline friends still shows up taking the space of a online friend still. (No friends are hidden though, it's just visually unpleasing)

EDIT : It also tend to still show offline friends as online.

Checking the "Show offline friends" and unchecking it, solves it.
