[CLIENT] wrong masteries displayed in NCS

Sorry if this is in the wrong place, I checked the post on how to submit.

I went to play a game as adc in the new champ select and checked that my masteries were my standard AD masteries, but as soon as I got into loading screen I saw that I had 0/12/18 masteries instead from the previous game. Screenshot (http://imgur.com/Irgtu2K) shows the problem in full detail, the actual selected page is "tank", while the client is saying I have "damage" selected.
