Two events very close in time with wrong state

Configuration
1

I have noticed from the Home Assistant database tabled called Events that two events got fired by Ecobee component with time difference in milliseconds has wrong status. See below 3 events; event first and third are the events I am talking about. I was expecting third event should have old_state cool not idle. Can some one explain what I am missing here?

Configuration:
  - platform: template
    sensors:
      thermostat_downstairs_current_status:
        value_template: '{{ states.thermostat.downstairs.attributes.current_operation }}'
