when using guide by the sports category i can't see sports later in the day

When i go to guide and select "sports" category i can only see what is playing currently. I can't scroll over to the right and see what is later on in the day. If I use the "all" category I can see what is going to play later for ALL the channels but not just sports category. The same with movies. If you go to the movie category you see "ON NOW" but you can't see what movies are playing later. This seems so basic!
