FINALLY I figured this out, since I got my iPhone 6+ 128 GB (and this should also be true for iPhone 6 users), when I have been turning my phone horizontal (landscape mode) it would fill up HALF THE SCREEN with the bookmarks, favorites, blah blah, and no matter what I did in settings or trying to edit it was still there. I JUST GOT RID OF IT!!! Lemee know if this helps for iPhone 6 users, but for 6+ when you turn your phone horizontal in safari go to the top where the URL address is, and to the left up there (not in the favorite bookmark area) is an icon that looks like an open book. Just tap it and it gets rid of that f$&%in bookmark take up half your phone screen!
