ViCare Gas consumption shows not the price

Hi,
i have importet my ViCare WLAN Module.
The sensors i have connected to my energy tab are the sensor.vicare_hot_water_gas_consumption_today and sensor.vicare_heating_gas_consupmtion_today.
I see every day my consumption.
On the energy configuration i set a static price to the sensors, but in the energy overview a can’t see any prices for the day.

ok, i don’t no why and was i have done,
I deleted the sensor and assign it again and now it works.
