Unable to set Fuel Amount @ Nordschleife in Freeplay

As the title says, unable to set the Fuel Amount @ Nordschleife in Freeplay

It just says calculating and even if you put it to 1% when you enter the race the fuel load is 100% (4 Laps)

Update:
It seems to be working today, it just takes some time to calculate.

Only tested it on one car and will see if it’s still an issue on others
