I have noticed the same thing going on. Whenever I try a new DG I can get acheivements, but only in the first match. I know for sure that I have gotten several others, but since it wasnt the first time playing that DG I didnt get them. I think I know what is going on, it sounds like the file that saves the info is stuck in a "read only" state, and cant be undone. That is if it saves all the info for each DG seperatly.
