The pick button for champ select is broken

For two of my promos games I ran into a bug where I could not lock in my champion at all. The first signs would come during the ban phase where my ban button would be greyed out and not work however because how that phase works the champ I hovered would get banned. However during pick phase the same thing happened and I ended up not picking my champion dodging both of my promo games because of it. Now I'm sitting with a half hour timer so a fair warning to u all if this happens u need to restart ur client.
