Sniper 50 headshots over 150 meters not tracking

I had the weekly challenge of getting 5 headshots over 150 meters tracking but the overall 50 headshots over 150 meters do not track which means I am unable to unlock my gadget for snipers. I restarted the game, restarted maps and nothing worked. I turned off my computer and restarted and it still did not work.  This is some really odd bug that tracks SOME challenges and not all even though it's the same thing (headshots over 150 meters).  My other challenges DO track which is even more weird.
