I can't change my runes in champ select

Whenever I am in champ select prior to a game, I cannot edit my personal rune pages to work according to the champion I would like to use in game. I can switch between my personal and the pre-made pages, but I cannot make any changes to them. However, I can make changes to my personal rune pages prior to loading into a game on my profile. This is inconvenient, however, because it does not allow for me to pic the exact load-out for the champion I want to use in-game if I am trying to counterpick.
