The video description on my AppleTV App is cut off. Why?

The description is cut off only when navigating a certain way. The AppleTV remote control does not have regular up and down buttons which trigger up and down movements of a specifc dimension but instead allows the user to scroll fluidly, without specific jumps/steps, by finger swipe. This means that with every finger swipe it scrolls to a different position. This is why sometimes it looks like the description is being cut off, but actually this is only because of the screen position.
