Xfinity TV Remote app needlessly duplicating favorite channels

My question is about the creation of a favorites list with the Xfinity TV Remote app. I like the idea of identifying favorite channels rather that browsing the entire list. but a quirk (bug? feature?) off the app needlessly creates duplicate favorite signal source entires when they have more than one channel. On my own list, for example, I can save 803 - PBS as a favorite, but it automatically adds it again then with a four digit channel number later in the directory. If I delete the four digit listing, it then also deletes the channel where I wanted to save it, at 803. So the process lengthens the favorites list, which is the opposite of the goal of having a shorter list of favorites. Has anyone else observed this, or better yet, found a work around? Thanks!
