STILL broken since release! Deadeye 1

Minus 2 billion out of 5000. Can't bring it down as it resets after each match to that same number. This has been a bug since release. They haven't even acknowledged it and I know it has happened to a fair few people. Just not most. This completely locks me out of unlocking the final sniper rifle and can never finish this challenge. Been another patch today to focus on the challenges and still this is here.
