Event won't trigger automation

I recently got a Shelly Dimmer 2. Today I installed it and tried to automate the light. My problem now is that the event of the input buttons won’t trigger my automation based on event type. If I remove the event_type, it seems to work, but without filter for long presses.

These are the trigger of my automation

# Works
  - trigger: state
    entity_id:
      - event.shellydimmer2_kuche_channel_1
    id: bright
# Don't work
  - trigger: state
    entity_id:
      - event.shellydimmer2_kuche_channel_2
    id: dark
    attribute: event_type
    to: single
# Works
  - trigger: state
    entity_id:
      - event.shellydimmer2_kuche_channel_2
      - event.shellydimmer2_kuche_channel_1
    attribute: event_type
    to: long
    id: "off"

I can see the events fired in Logbook and Events section on the device page.

Is there a way to see more details of the events fired? Has anyone a clue whats going wrong here?

This is a known issue:

I ended up using the pattern from the docs https://www.home-assistant.io/integrations/event/#event-types

This is the final automation
