Deranked in Ranked for winning

I’m racing with a bunch of friends, destroying ranked adventures, and guess how many points we get for winning the first championship? We got 4 points.

Okay, maybe it was a glitch, we load up another adventure, win that one within 20 minutes, and guess how many points we got this time? 0

We got 0 points for winning a ranked adventure. My friend lost 100 points for winning the adventure.

What kind of system is this? Honestly? We don’t get to choose who we race with, so why do we get penalized for beating them regardless?
