Duplicate Notifications from single Trigger

I have created the automation below which will take a snapshot and send it to my phone and my wife’s phone when my doorbell camera detects motion. The doorbell is an Amcrest AD410 which is integrated using amcrest2mqtt. The binary_sensor.doorbell_motion has a timeout of approximately 1 minute (e.g. it will trigger “on” and stay on for about 1 minute before turning “off” if there is no motion).

I have found that in some instances I will get two notifications at the same time with the same snapshot (see attached screenshot). I seems to happen randomly (I have not been able to reproduce it at will).

Any ideas why we would get duplicate notifications?
