headshot challenge not counting

So i've been trying to get the SVDM which is the first sniper challenge, I just did a game with 28 headshots with a sniper (the challenge doesn't require a distance, just 100 headshots) and my count didn't move. The challenges are already hard enough, how will we get awarded for all the things we've done that are not counted in the challenge ? I'm not trying to spend 100 hours on a challenge and get nothing once it's fixed just to have to try again.

I'm already way above the 100 headshots since I unlocked the challange
