Weird Friends List Encounter! :O

Is this weird or what?
As you probably already know, I comment my friends on my friends list with their names. All my friends have their name in the comments. While I was in the middle of writing my new friend's name on my friend list, it was very slow. I waited patiently, but the the 'Group' button was no longer named 'Group'. The Group button had turned into my comment. Weird, right?
