Weekly Challenge XP not adding up

So I’ve noticed this for a while now and just haven’t felt like bringing it up. Sometimes when I finish a weekly challenge (or even daily) the panels will SHOW +5000 XP but then my progress bar will show a total much lower (I.e. 1400 XP). Am I missing something here?

I have the same issue here.

I also notice the daily xp rewards are not paying out either today for me.
