Masteries Not Loading Correctly With New Champion Select

When adding or deleting mastery pages, then going into the new champion select, the old masteries show up, but are not usable. When I went into the champion select with bot (ADC) as my role, I wanted to choose to use my new ADC mastery page, leading into the keystone - Thunderlord's Decree. Instead, what happened was the mastery pages I had recently deleted were displayed. I decided, since I was playing Quinn, to choose my old "Graves" mastery page, thinking it would still give me the masteries I needed (Thunderlord's Decree keystone). I made sure to check that the mastery page would still give me the correct keystone, so I clicked the pencil (edit) button, but was displayed with a blank page where the mastery page SHOULD be. A picture of this is shown here. When I got into game, I had the Bond of Stone keystone, obviously my new tank support mastery page. After the game, I attempted to assure my mastery pages were inline, but my entire "Click to view/edit your summoner profile" section of the launcher became blank and I was unable to click any other tab of my summoner profile after selecting "Masteries". All of these problems were fixed with a simple logoff-login (turn it off and back on again haha). I hope a riot employee can fix this soon so others will not be faced with these same problems.

Thank you, FrostBite NWS
