Guide problem

I chose all channels on "guide" but it doesn't stay. It keeps going back to "free to me" setting. When I input a channel for example 005 on the guide it will show me what's playing on 005 in whats playing on 006 and so on. I will pick 005 and it will take me to watch the program. When I go to Xfinity- guide it will take take me to channel 805 . Why can't I just go back to 005 where I was like normal TVs. I will hit the guide button and "free to me" is selected. But In settings- preference-general, default guide is on "all channels"! Is there a fix to this?
