Trending Fictions

I don't think this is a bug (might be wrong) but on the front page in the Trending Fictions thingy there are 9 novels. You see 5, then it rotates and you see four new ones and one carries over, so one of them you see twice. Shouldn't there be 10 novels so 5 each time? The double exposure for one novel isn't a big deal (sometimes it's my own novel that gets it) but it just bothers me. I'm easily distracted when I should be writing (like now).
