[BUG] Guide's "HD Channels Only" doesn't show all HD channels

Guide Issues

On the Web Client version of the guide: Selecting HD Channels Only in the guide results in several missing HD channels (namely 6.1, 8.1, 10.1, and 10.2 which are CBS, NBC, and two local PBS stations broadcasting in 1080i and 720p respectively) and includes several that should not be displayed. If you move into the future in the guide and then toggle between All Channels and HD Channels Only, the guide resets back to the current time. Why isn’t there a “View Primetime” option?
