Error While changing summoner spells in Custom Aram Games.

I would like to report an error i keep getting for every custom game i play when joining a custom lobby. While in champion selection my summoner spells are always Cleanse and snowball by default and i can't change them instantly as i can anywhere else, sadly this has been going on for the past 2-3 days it has been occurring in custom Aram games. I tried to repair the client twice hasn't done anything to fix the error if anyone can help i would appreciate it.

Ty for your time.
