Festival Sprint - No options show up in Buy Car before race

I just started the Fall Festival and am attempting to race in the Festival Sprint (doesn’t matter which race I choose). I choose Continue Event then it brings me to the Buy Car option because I apparently have no cars for this event.

Issue: Once I select Buy Car, there is nothing, no cars or options to choose from. It only shows Performance at the top with all the ratings for Speed, Handling, etc. as 0, with question marks for rating and what kind of transmission. So this race is not possible to run without being able to select a car to use. Anyone else seen this issue before? In this race or another event?
