Another Challenge Not Tracking

As the "new" (11/5) weekly challenges rolled out so I started playing. I got most of them complete then realized that one wasn't tracking. I don't think its just a bad description, such as needing to be on a contested flag, it's just not tracking. I've completed other challenges as engineer, like dealing explosive dmg to vehicles, and they tracked just fine. 

I've run out of rerolls so I can't just try a different challenge, I'll just be out of the 5 BP tokens

I've also noticed how on week 1 I have 10/11 challenges complete even though I did all and the timed challenge

I play on PC through Steam if that helps. If anyone else has noticed this please feel free to comment or make your own report. Thanks
