Guide - Movie Chanels That I Don't Get Appearing on "Channels I Get"

I have the Guide option configured to only show me the channels I get (selected "Channels I Get" from the Favorites List.  However, there are several movie channels (specifically, some HBO, some Cinemax, some The Movie Channel, Sony  Movie Channel, & Shorts) displayed that I do NOT subscribe to.  Is there a reason why these channels show up when I select "Channels I Get" from the Favorites List?

Thanks!
