Issues trying to airplay to TV

I've got a pretty simple setup based on a great package on these forums, but I'm having an issue with airplay. My goal is to be able to quickly select my TV as an airplay destination for my lapop through a Touchbar key.

This is my current setup -

When I tap on the button, it opens up System Preferences, Selects the first item in the airplay list, then closes system preferences. The only problem is that it selects the first item, which is a device I don't even own.


I've searched around and can't find the ability to remove those other devices. Has anyone ran into this issue before?
