Rune page/mastery page mislead after rejoining a game that was prev canceled.

So i just got finished doing a game, had changed my mastery page last game and forgot to change it this game, but get this, it said i had the mastery page from the game BEFORE the last one i played. I was of course trolled and given the wrong mastery page. The names stayed the same when it should have changed to the page of your recent last game.
