the colony DLC has disabled my stat tracker

right after the dlc colony was installed I set about getting gold on every mission.needless to say palmer’s pure gold did not unlock.
I tried the hard reset but no change
I have been re-playing & have finished the first 7 missions & no change
halo waypoint shows I have no medals except a silver on mission 12
I have a new console. now I regret replacing my old because I don’t know why this is happening
