I just found out that the cycle of fuel consumption units in the “Units & Values” stops at “L/100km”. I think the app does not recognize the “L/100km” because the liters is capitalized.
I need to manually change the L/100km to l/100km
l/100km > km/l > mpg > Wh/km > Wh/mi > L/100km (and the cycle just stops but the text value works just fine)
