Remote Shortcuts - Live TV option Missing

Under the Remote Shortcuts option, by default F2/Red Button is set for Live TV.

If I change that to Guide, for example, there is no way to get Live TV back as an option for that button or any other button. All buttons have the following: Guide, TV Shows, Movies, Library, Schedule. None of them have Live TV as an option to select.

Am I missing something?
