hextech crafting

I just bought 2 keys so I can open those boxes that had been lying around for a while. So i open them I get nice 2 skins. So i buy 2 more of those keys and 1 mystery champion shard and would u believe i get 3 galios from those 2 boxes and 1 champion shard :D. Now that wouldnt bother me if I could reroll them into random champion but it seems to be bugged or smth, I cant reroll those 3 galios. When I press reroll button all the galios seem like they would do, but I can't click furthermore. I just can't reroll them.[slayer-jinx-unamused]
