champ select masteries bug

sometimes the name as listed in the drop-down for masteries is incorrect.

for example right now, I recently deleted page 3 of my masteries, but it is still listed in the drop-down. if I select the page titled "graves" in the drop down, it selects the 7th page, which is actually my "wukong" page I have to select the page before it in order to select my "Graves" page since it's now page 6.

I've also previously had the same bug happen, where i updated the name of the pages while in champ select, and the name isn't updated with the drop down.
