[CLIENT] Alpha Champ Select Mastery Change

I noticed twice now during champ select when I go to change my masteries I cant view the mastery tree I have selected, it will only show the previous one used no matter which one I click on. However in game I have the right masteries.

Sometimes I change my presets and want to tweak for a different champ. Currently I cannot, unless I start from scratch.

I run a higher end PC and do not have any client lag as I see some other people are having.
