Aerial Combat expert

So for the mission "get 10 kills with aircraft at objectives" it gets stuck at 8 so even if i kill people from the roof of C in Eastwood map with either as a helicopter pilot or as a door gunner it never adds up. Also weird if I want to track the mission it doesn't want to track and every time tracks the first mission in the list instead. Also when I arrow down it just skips over the aircraft combat expert mission to the mission after that on the list ... weird. Did anyone experience this also???
