Hey Folks! I’m the creator of the integration with Home Assistant. This isn’t a SmartThings issue. It’s a quirk that occurs when the integration is removed in Home Assistant before removing it in the SmartThings app. It also happens if you reverted Home Assistant, removing the file (.storage/smartthings) which contains the identifier to identify the SmartApp, so then the integration creates a new one. This is by design as the integration allows any number of Home Assistant instances to control the same SmartThings Account.
See https://github.com/home-assistant/home-assistant/issues/21462 for more information.
The good news this can be cleaned up and I’ll write a utility this evening you can use to remove the orphaned instances of the SmartApp/Automation.
Thanks for your patience!
Andy
