Rune Pages

When in ARAM champion select the rune pages default to the primary rune page that is appropriate for that champion, meaning that if it is an ap champ, it will default the sorcery page, a tank will default the colossus, ect. I do not have custom pages and it will not display any of the other rune pages. If I reroll my champion or trade my champion with another player it retains the rune page it selected by default for the original rolled champion.
