Topic: Custom career cars in NASCAR Rivals

I just created my own team in NASCAR Rivals after racing with other teams for two seasons. I was looking forward to using a custom car design I had spent a lot of time making. After I selected my sponsor (Mobil 1), it continued with the tutorial, and I never got a screen asking me to "Edit Car Style," as I had seen in gameplay videos. When I went to Daytona, it showed me using the same car I used in the previous season. Has anyone else had this problem, and is there a fix? Thanks.
