Recorder. How exclude events?

Configuration

Hi, I would exclude these from Recorder
image_events

They are events fired by an IKEA Styrbar Remote Control paired with deCONZ (no entity_id).
I tried with:

recorder:
  purge_keep_days: 5
  auto_repack: true
  exclude:
    event_types:
      - remote_button_long_press
      - remote_button_long_release
      - remote_button_short_release

just to try, but it doesn’t work!
Do you have any ideas on how to proceed?

Thanks
