Utility meter and original sensor not showing in energy dashboard selection

I am wondering if anyone can help. I have an IotaWatt that is working well and is integrated to HA. It provides me with a sensor called sensor.mainsexport_wh that shows how much I export to the grid (from solar production). I previously was able to select this sensor and add it to the “return to grid” section in the energy dashboard. I recently added a utility meter to break down the rates I get for solar return (I get certain rate for the first 10kWh a day and other rate above it so I defined two tariffs - high and low). However, after adding the utility meter, the original sensor stopped showing as an option in the dashboard and the utility meter sensors are not showing either. I have other sensors from the IotaWatt that work fine, including my grid import sensor which is also defined through a utility meter and works fine. I tried removing the utility meter but to see if the original sensor will come back but it hasn’t. What can be the problem?

The sensors are:

The utility meter configuration:

utility_meter:
  daily_solar_export:
    source: sensor.mainsexport_wh
    cycle: daily
    name: Daily solar export 
    unique_id: utility_meter_daily_solar_export
    tariffs:
      - high
      - low

Update:

I removed and reinstalled the IotaWatt integration and now I can select sensor.mainsexport_wh in energy dashboard but the utility meter sensors (sensor.daily_solar_export_high and sensor.daily_solar_export_low) are still not showing up as options. I have no problem using other utility meter sensors (which are also based on a IotaWatt sensor) in the energy dashboard. Other than different names the two utility meters are the same.

Does the energy dashboard require energy measured in kWh?

It works with both kWh and Wh. All my other sensors are Wh and working.
