I came up with something that works with my remote, but it is not very intuitive. Under the 9 is a button with 3 horizontal dots (...). If I press that button while watching local stations, I get a small screen popup labelled "More Actions". Then if I scroll down to "Channel List" and press OK, I see another screen on the left labelled "Channels". If I then scroll up to the right corner and highlight the three vertical dots, I see a "Filter" screen. I then go down to "Channel Group", and the dropdown shows the Favorites lists, which I have renamed through Channel Manager>Edit Favorites.
Perhaps someone has a more intuitive way to do this. Hope this helps!
