Energy Dashboard - Costs disappeared?

Hi to the community,

I have an issue, that suddenly the energy costs in the energy dashboard are not displayed at all (see screenshot). I’m using a sensor for the price/kWh (see second picture) and according to the developer tools they show the correct price/kWh. Even setting a fixed price in the configuration displays no costs?
(even no zeros … there is literally no cost :/)


Could someone give me a hint?
Thanks in advance!
