Can’t change images in pages

I created a page, for example “about”, I imported the layout of my theme (zeever), but in the edit mode, there is no way of changing the image because it doesn’t even appear. I also can’t delete the title. So if I copy a normal template, and put my image and title, it appears double even when in the edit page I only see the photo I put. I need help with this.

The page I need help with: [log in to see the link]
