Unwanted section after Post

Hi
My website address is thebannutimes.com . I have started it last night. when I open any post then related posts are also seen after the post. These posts are without featured pics. In the Theme setting option when I disable it even then 3 related posts were visible. When I share the post on facebook then even there the word Related comes above the website address.
How can I disable it so that it is not visible on FB shared posts. Here is the link on a post.
