When you go to select a new banner, the box has the text AFG+ Premium Banners and Standard Banners. Sometimes when you scroll down, the text doesn't scroll with it and stays in the background, so it can be seen in between the pictures of the banners

That doesn't happen to me. Instead, I merely can't keep any banner I choose because I see no option to save the banner I've chosen. When I choose a new banner, I see a preview of it, but when I exit out of the selection of banners I still have the same old banner I had formerly.
