Mixing addon cars in races

[sw3gameboy]

This is how it looks like in MCC:

As you can see, they both have the SAME menu class, race class and price. Still doesn't work

If you have only both cars in this race class 100 that should works (you can sort by race class to verify that) but if there's more cars the AI choice could be related to folder name but I never verified if with score to open is like no score to open
