[Champ Select] Proper skin not being remembered

I've been playing a lot of aram lately, and I've been noticing that champ select is not remembering the skins I want to use. For example, I have both galactic and infernal nasus. I always try to use infernal nasus, but it will always have galactic nasus selected. It does the same thing with garen, where it gives me dreadknight garen instead of warring kingdoms garen. This is 100% reproducable in ARAM whenever I get a champ with more than one skin.
