Tracking challenges says 4/4 of but can only see 3

Just as it sounds. In my "tracked" challenges I can see 3 but it says there are 4 challenges currently being tracked. Annoying because now I can only track 3 at a time and have absolutely no clue what the 4th tracked challenge is. Even if I untrack everything it still says I have 1 challenge currently tracking. Any fix in sight?
