Calendar automations triggering inconsistently

Configuration
1

I have several automations that are triggered by a calendar event. These had run last year but recently have stopped working. Going into the automation and attempting rebuilding them revealed that process had changed from a “State” selection to a “template”. After getting to know the new methods, if have found that some of the re-written automations do not trigger. I am creating test events in the calendar to trigger thes automations and yes I refresh the calendar and make sure the test event is present. Here is an example of an automation that worked.

alias: 005-MLK Day
description: ""
triggers:
  - trigger: calendar.event_started
    target:
      entity_id: calendar.holiday_lights
    options:
      offset:
        days: 0
        hours: 0
        minutes: 0
        seconds: 0
      offset_type: before
conditions:
  - condition: template
    value_template: "{{ 'MLK Day' in trigger.calendar_event.summary }}"
actions:
  - type: turn_on
    device_id: 30452fa9920632e6321742a622e3ed96
    entity_id: f07975f7976bd9b1320ef6643d35dd0a
    domain: light
    brightness_pct: 100
  - device_id: 30452fa9920632e6321742a622e3ed96
    domain: select
    entity_id: 0611fc262ceb925443e2659acec6549d
    type: select_option
    option: 07-MLK
mode: single

Here is an example of an automation that does not work:

talias: 001-New Years Day
description: ""
triggers:
  - trigger: calendar.event_started
    target:
      entity_id: calendar.holiday_lights
    options:
      offset:
        days: 0
        hours: 0
        minutes: 0
        seconds: 0
      offset_type: before
conditions:
  - condition: template
    value_template: "{{ 'New Years Day' in trigger.calendar_event.summary }}"
actions:
  - type: turn_on
    device_id: 30452fa9920632e6321742a622e3ed96
    entity_id: f07975f7976bd9b1320ef6643d35dd0a
    domain: light
    brightness_pct: 100
  - device_id: 30452fa9920632e6321742a622e3ed96
    domain: select
    entity_id: 0611fc262ceb925443e2659acec6549d
    type: select_option
    option: 03-New Years
mode: single

I don’t see a difference.

Are you also refreshing the trigger listener by reloading the automation?

While it can be done by editing and saving the automation, I usually just use the Action tool with an action like:

action: homeassistant.update_entity
metadata: {}
data:
  entity_id: automation.example

There is also a typo in the second automation: talias instead of alias.
