Mastery bug in champ select [client]

During champ select When picking a mastery page regardless of which one it was it would only show the setup for my mundo page. I attempted several times to switch pages and it was the same for the majority of my pages. I could not take off points from the page and it would not allow me to reset. right before my game started a message saying something along the lines that i have been disconnected from the server popped up and that was the reason for the mastery page issue. When i got into game it wasn't even the page my mastery was stuck on or the one i had attempted to pick. I played a game after and it was a similar issue. My first few pages were stuck on 1 page and still could not change anything on the pages. I was able to use my support page but it still would not allow me to change the points that were already set.
