Assetto Corsa rain tyres in custom championships

[TinMan_JB]

Hello, fellow simracers!
Rain tyres and wet physics in AC (using CM & CSP preview) work in single races/weekends/practice, but not in championships. Is there a hidden setting that enables use of rain tyres and wet physics in custom championships, made with content manager?
If anyone knows sth, I'd appreciate the info!
Regards, J.
