Negative value for reference consumption

I’ve been using ABRP for about one year now, without any issue. Since the last month, it’s impossible to plan any trip because the reference consumption of my car has a negative value and ABRP gives an unrealistic estimates of charge values at the arrival. My car is a Nissan Ariya connected by Enode and the app is running on Android. I tried to set the value manually, but ABRP doesn’t accept it ( label gets red ). Any hint to solve this ?
