[New Client] Mastery Pages are re-arranging themselves.

Hi, so after finally letting my OCD take over, and sorting out my whole 20 Mastery Pages so they're in order from Top,Mid,Bot,JG, making it easier to select them within champ select, I've noticed upon pressing save, they change their positions. I've tried to order and save them about 10 times now, hoping eventually they will stay the way I want them, I thought I finally got them to, until I went to the store, and then back to my masteries to see they were out of order again. I understand for some players this mightn't be that big of a deal, but the feature to order your pages was included in the new client, and it's a feature that does not currently seem to work. Thanks for looking into it guys? :)
