Slider has one image only, how to fix?

I try to make slider with 3 pictures as on demo site but works only one.
I use three images in header setting theme. Also I made dynamic sidebar “Home Header” and pick it on page setting. Add widget Query in the sidebar as well. But just have grey background without listing pages. What have I made wrong?
