Changing 2 car league to 1?

I've just started a league but I want it to be for one car teams. How do I change it from two? There was no option available when setting it up, and there's no option now. ?

There is an option when you set it up, but it can’t be changed once created

There was NO option I saw and I've spent money to buy the 50 tokens!!!!

Dude, it’s in advanced settings, when creating a league, where you set race duration and race speed, it’s right there. 

“Cars per team” default is 2, you can toggle to 1

I know but you assume there will be advanced settings after you've started the league. There is but the choosing the number of cars is missing. 


Ok, so now I want to start again. How do I delete or close down the 2 car league so i can start a new 'one car' league. It won't let me have two leagues. What a mess?

Make it private so nobody can join, quit the league and after few hours it will be autodeleted for lack of activity.

Thanks. ?
