Catch This achievement totally messed up

[joniam00]

A few months ago after an update, my catch this count went from in the 200s to the tens. Although my medals stayed the same, my achievements did not and started building to the 500 again. My medals show that I have more than enough for the achievement, but will not unlock!!!! Why hasn't this been fixed? Also on matchmaking, I never get credit for my steaktacular, or triple doubles in halo 3 or halo 2 games. It shows the medal after the game, but not on my over all medal count. Why not?
