backwash FS Pop Shuv-it to grind

The FS Pop Shuv-it to grind objective is broken on the backwash challenge. It won't award the player after they complete the attempt.

P.S.

I'd love to see more challenges that doesn't have the all in one attempt objective. Or better yet, another way to earn money and XP other than challenges, tasks and crackin loot boxes.
