I’m trying to implement a notification group using the instructions here: Introduction | Home Assistant Companion Docs

When I try similar YAML, I get “duplicate key” warnings for the “service” entries, like this:
I thought it may have just been Studio Code Server giving warnings incorrectly, but it does behave like duplicate keys, where only the last one has any effect.
So what am I missing from that example that I can’t figure out?
