Can't find the Chord Editing dialog in Inspector

The manual says that I can edit chords using the Chord Editing section of the Inspector. I don’t see a Chord Editing dialog at all in the Inspector of the chord track, the MIDI track that’s following the chord track, or on the chord symbol itself.

Here is the picture in the manual:

Here is a screen shot of my chord track with Inspector:

Here is a screenshot of the MIDI track that’s following the chord track:

As you can see, nothing I’ve found in Cubase resembles the picture in the manual at all, and I am at a loss on where to find the Chord Editing dialog.

I appreciate any help.

That is refers to editing actual chords in the Key and Score editors, not chord symbols on the Chord Track.
