Horisontal stack with buttons

I have a problem with a horizontal stack card and three buttons.
what ever i do the toggle action is removed on button thre, the one with entity and not call-services.

type: horizontal-stack
cards:
  - type: button
    tap_action:
      action: call-service
      service: nissan_leaf.update
      service_data:
        vin: REDACTED
    icon_height: 45px
    icon: 'mdi:reload'
    name: Oppdater
  - type: button
    tap_action:
      action: call-service
      service: nissan_leaf.start_charge
      service_data:
        vin: REDACTED
    icon: 'mdi:flash'
    name: 'Start Lading '
    icon_height: 45px
  - type: button
    entity: switch.leaf1raym_climate_control
    show_state: false
    name: Varme
    icon: 'mdi:fan'
    icon_height: 45px
    **tap_action:**
**      action: ''**

Is there something wrong here, why cant i set it to toggle?
