As far as I can tell everything is working fine. The first game (12652131) was not rated, and I checked the server logs to verify that the players ratings did not change after that game. However the second game (12652187) was rated which is why you see different ratings on the game info for that game. You'll notice that the rating changes all correspond with team 2 winning the second game.
In particular note that Regisle and St3k were on the same team for the first game but different teams for the second game, and that St3k gained rating appropriately, because he was on the winning team for the second game. Same with Warcry616. If you click "show rating change" on the second game it should show you how much the ratings changed as a result of that second game.
