Custom Integration: Volkswagen WeConnect ID (Europe)

I have also the problem with the wrong unit “kkWh”:

My config:

sensor:
# ID.4 GTX Charge Energy
  - platform: integration
    source: sensor.id_4_gtx_charge_power
    name: ID.4 GTX Charge Energy
    unique_id: 2e013446-d576-4214-8c7e-af080c4e818d
    unit_prefix: k
    round: 1
utility_meter:
# ID.4 GTX Charge Energy Today
  id_4_gtx_charge_energy_today:
    unique_id: 725703e0-3611-4a73-be69-e78f516315bb
    source: sensor.id_4_gtx_charge_energy
    cycle: daily

Home assistant configured sensors:

Could this be that there is a problem with the “native_unit_of_measurement”?
