Seasonal events not working right when trying to play Co-op or pvp mode

So I just did Blast from the past on pvp mode and I have my settings set on unbeatable and I didn’t get credit for the event like the game side I should. Either 1 make all the events Solo only so everyone that plays the game don’t get screwed or 2 for the people that have their settings on new drivatar to force them where they can’t join a race unless everyone is on the same setting. I’m getting tired of trying to join 50 billion races to get a special price and I can’t get it because of one person not setting up right for the group.
