Dev traits not revealing

It does initially register but I have found that if I leave the league (to play a different game mode or just to take a break because someone else hasn't played their game it will reset back down to zero even though if I look in stats under downs played they have some downs played. Furthermore there isn't a way to turn this "fog of war" off to see them and I am worried that it is going to affect the ability slots they may earn in progression.
