I reset my Valour rank earlier today, and since then have gotten back to Brave I and not a single one of those rank ups has tracked in the Challenge.
Friend of mine is having the same issue but in Gambit, which I finished before weekly reset and still worked at that point.
ETA: oh god I think I found it. It's either lagging behind OR I had to go and pick up my rank rewards from Shaxx.
Good god Bungie that could have done with some communication
