Past Mastery Page Used in Champ Select, Despite Selected Page

Anyone else been getting the wrong page in champ select masteries in game? When I edit a page, and save it, I'm getting the page I edited, however, the page that I select is clearly displayed in champ select as the page I want.

I also noticed that at least one other person had this issue happen to them in game, with no masteries at all selected for the guy. We were all very unhappy.
