Since it is "built-in", I am guessing it cannot be deleted. My copy has several places where the track is not connected to a station; therefore the sessions do not run. When I edited the Route, I was not presented with the option to overwrite existing and do not overwrite session. instead, it created a duplicate route with no sessions. How can I fix, or obtain an unbroken, built-in route?
You cannot delete "built-in" content but you can disable it. In CM search for <kuid2:354694:1009:5> right click the asset and then left click "Disable\Enable" that should stop it from showing in the tracklist.
