Setup bug

I changed the setup and saved it but when I returned to the setup menu I saw that the setup wasn't saved...now every time I try to change the setup it doesn't work

Hi Mirko, you've purchased the ideal set up for your drivers, which automatically adjusts itself based on the track's weather conditions in real time.

Any changes you make will be overridden by the ideal setup option you purchased, which will automatically pick the best possible set up for you.
