Champ select major Bug

I had a bug in champ select so weird and helpful (Note only once happened) I could see my teammates profiles :D
http://imgur.com/ufoXLSB I dont know how the hell this happened but can we make sure this never happen again I already Reinstalled the Game And sometimes I get some bugs when I enter the game where my health bar on the HUD is black and I get an extra black icon of a virtual teammate A black sphere I dont know what can I do to fix such these things....

Peace
