2nd player can use DLC bikes now

I bought the game 2 weeks ago to play with my son and I bought the 2025 bike packs thinking we could both use them and that wasn’t the case until today. He has only been able to use the bike that come with the game but today while we were playing the game crashed and showed and error code and after rebooting the game he now has access to all of the DLC bikes I bought. Had this happened to anyone else? Just thought it was really weird that he hasn’t been able to until today when the game crashed and as far as I can tell there was no new update today
