Top pane preview

On channels HDHomeRun app for Apple TV. It gives me a preview of what’s on in the top shelf when I’m on the Apple TV Home Screen. How do I change what is shown here? Shows ‘on now’ but ideally wanted to set to Hd only. I remember there being a setting before but maybe only on the server paid version version. Not the HDHomeRun.

It shows the channels which have been favorited within the app
