Can someone explain the proficiency in this game?

Since every post with a picture here result into insta removal im gonna type it out. I just finished a game of ranked with two quick rounds. I feel I have been stuck centurion for weeks now and I play much Iron man but still it says I have 9/60 minutes played. Last game I got 19 final hits and it says I have done 14 final hits total. What is happening here? Am I missing something or its just bugged?
