Energy / Shelly EM - unable to select entities in the "Consumed Energy" drop down

I have spent the last 6 hours Googling and reading through the HA community but everything seems to refer to pre 2022.2.8 release and doesn’t work.

I’m using Shelly Native (Not HASS / HACS)
Shelly Energy Monitor working perfectly on Shelly App
All Shelly devices and entities within HA working and no errors
Nothing Disabled
When trying to add Shelly EM I am doing the following:

Energy >> Add Consumption >>

However when I come to the “Consumed Energy kWh” drop down - I can see six entities (sensors) but i am unable to click or select any of them.
I have tried (as someone suggested on another thread) to add this:

homeassistant:
customize_glob:
sensor.*_used:
last_reset: ‘1970-01-01T00:00:00+00:00’
device_class: energy
state_class: measurement

… but that doesn’t work either.

Any help on how I can get this EM setup without using MQTT would be really appreciated.

Thanks
