i completed all the challenges on 6 and ranked up then after a few missions it said i was rank 2 i already completed the missions so i ranked up again to 3 the only challenges i dont have completed are solo and fire team ops with a bonus focus but completing those missions does not progress the quest i recently came back to the game and did notice the while i was rank 6 all the quests in rank 4 and 5 weren't completed
