Energy randomly create new Electricity recorder


I’ve noticed over the last couple of hours, that the cost on the Energy page suddently resets the cost total (after a HAOS reboot). I then look at the Statistics (recorder) for the Electricity cost calculations. Two new ones are created automaticlly, meaning no historic cost data anymore (kWh is still maintained). This isn’t the first time this has happened for me. How do I ensure, that this doesn’t happen? … and are there any way to get the data back?
