This challenge is absolutely busted mine has been stuck at 8/10 EVEN WHEN I WIN ALL ROUNDS! It's frustrating to see it still in my challenges list.
The progression seems to be hit or miss I remember having to go advance through some extra rounds of Gauntlet during that week because some of them weren't registering, if the next's week has more BR/Redsec challenges I think I'm prett much done with the weekly challenges as it is essentially not respecting my time as the mastery grinding for weapons is also suuuper slow past level 20 and level 30 and up is even slower, this feels so much like a F2P game disguised as a 70$ USD game because the more time passes the more I'm feeling like I'm playing a Chinese F2P game with dumb challenges that are just massive time sinks
