STORE Glitch[BUG]

I found a bug in the store, when you go to the store, and unpick champions owned and not owned then sort to champions, if you click champions a lot... the bug will occur, the champions name will show up the times you clicked it. My friend says it doesn't work for him though... so i think it maybe occasional or something along those lines. anyway this is not game breaking but i wanted it fixed, it [Buged] me a lot. :D that's my bug, here is a screenshot: ps: i did this on my smurf just incase you are alarmed.
