Double drivatars = double championship points

Hello, could someone please help me with this double drivatars in this seasonal championship. I want to get the rewards before it’s too late, won every race in the championship but still ended in second place because there were drivatars that were doubled (two cars with the same gamertag). Their points were merged at the end of the championship. I’ve tried to change difficulty to refresh the drivatars but it didn’t work.

With regards.
