This is really confusing to me. The History list shows when this automation was turned on and turned off (turned on means enabled, turned off means disabled) but the Logbook list doesn't show anything for this automation at the datetime it was enabled (it does show me manually disabling the automation, though).
I searched for the automation's name (e.g., automation.my_automation) in every file in HA's confg directory and there are no occurrences. I also searched for the automation's ID (e.g., 1623421375007) in every file in HA's confg directory the only occurrence is in the Automations.yaml file where the automation is defined. I also searched for automation.turn_on and automation.turn_off in every file in HA's confg directory and there are no occurrences.
This seems strange: when I click on the "On" or "Off" bar in the History list for this automation and the details for the automation pop-up (screenshots below), and I then click "Related", the section that says "Part of the following automations" lists about half of my automations, but none of them have anything to do with this automation.
