In champion select banning bug

Hi,

i have noticed that sometimes when im banning in draft mode_ i cant see some chamions_ when i wanted to ban zed i couldnt find him even if i wrote in search menu but when i was not banning i could see him .

same thing with rengar, yorick, zyra, zac, ... and probably* with other chamions that i didnt noticed and no they were not banned yet.

I dont know how to reproduce it but it happened several times.
