Mini Guide behavior

For xfinity TV x1 box, there is a setting to select your default view. I set this to be my Favorites. But when I Arrow Right to the Mini Guide, I often see channels that are not in my Favorites.

If I press Guide Guide, the listing (limited to Favorites) is correct but the Mini Guide doesn't reflect default Guide...except sometimes it does. It's inconsistent so it's difficult for me to think this is intentional and not a bug.

I would prefer to see the same channels in the Mini Guide that I see in my guide (not Fox, not Spanish).  I replaced the box but the behavior is till the same.
