Duplicate keys when trying to use notify groups

Configuration
1

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

Specifically, this is the example given:

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?

Well, that definitely explains it. Thanks!
