Those are probably all some weird webpage caching bugs (yes, your profile etc. are all just webpages loaded from PVP.net)
Another related quirk is that you can't refresh viewing a friend's profile from the friends list if that friend's profile was the last profile you viewed in that LoL session.
(first viewing another friend's profile or your own profile before viewing that one friend's profile again works around that)
