Label Track not working?

I am using Audacity on Mac Mojave. I have noticed the Label Tracks are not working in this version. I highlight the section and can choose Label Track, which creates the track but without a label.
Any help or suggestions appreciated!

You highlight the section and use Edit>Labels>Add Label at Selection or its shortcut at Cmd+B to create a label

Tracks>Add New>Label Track just creates a new empty label track.

See this page in the Manual:


Amazing - thank you!
