Utility meter and Name usage - not working

I make simple Utility Meter badge to display current tariff but badge name is not represented by defined name. It is presented by sensor name: “dnevna_energija” rather than “Trenutna tarifa”. I tried with quotes, without quotes but I didn’t find a way to display defined name. Is it a bug?

utility_meter:
  dnevna_energija:
    name: Trenutna tarifa
    source: sensor.podno_kat_energy
    cycle: daily
    tariffs:
      - skupa
      - jeftina
