Wrong state class for flow_rate sensors

After updating to Preview 2023.09.19:

The flow-rate sensors have also problems with their unit:

SensorDeviceClass.WATER is not correct. It is meant for water consumption meters. There is no predefined device class for flow at the moment. Just leave it out, it is not mandatory.

Is this fixed?

With the update, I did not see these errors any more.
