CLIENT BUG-redesigned champion

I think i found a bug in the new champion select for ranked games . Before you ban champions there is time to alert the other players which champion would you like to play . It was weird when I saw Varus as an option although I never bought him . I clicked to chek if I will be able to pick him . After the bans were picked I was waiting for my turn to pick my champion. When my turn came , I just clicked pick and I picked Varus. Since I never bought Varus and he is not free to play I figured it is a bug . Hope I get a reward from riot if it realy is a bug :D Cheers
