Messed up Halo 4 stats?

Some people I know and I have experienced weird bugs in the stats. For instance, earlier today I played my first and only game in MM, yet the website says I have played two (or better yet, played one and quit another one).
This is the game I played and this is the game it says I have left. You guys at 343 should fix this asap as it’s going to make many people upset.

Bump, this is important.
