Sppok - trouble with incorrect notifications

Installed spook a few weeks ago, and it’s really useful. But a few times now, I’ve had messages that something needs fixing that turned out not to be correct. Today, for example, I had a message from spook that one of my automations used an action that doesn’t exist - namely, sending a notification to my wife’s old phone though the app. I checked the entire automation both in the UI and in YAML and spook is mistaken, because that action is definitely not used there.

Anyone else had this issue? Any clues about why this happens?
