Masteries/ Masterypages

Hey guys,

I just played some games and discouvered a new bug.

1. I join a lobby and pick a champion.
2. I choose my runes. 3.(heres the bug) I want to change my runes for my specific champion bug they wont change. I have 5 different mastery pages and If I want to choose my GP page it changes to my Lee sin page. The name is still the same but the masteries change. I dont know why. Ingame I they change aswell . This happens to all of my pages. The screenshot I showed is a graphic bug . The masteries have a small square under their name(?). I restarted my launcher and deleted all my pages and renewed them but nothing helped.
