When you share a link from WordPress or somewhere else, Facebook fetches the images and other content information. Facebook scrapes every URL that users and pages share and shows the featured image, title, and description. Facebook takes that information from either the title/description meta tag or, if not set correctly, it takes the first paragraph of the article, just like Google and sets it into a quality piece of content including image, small description and heading.

But because of some unknown errors the link previews generated while sharing your post is altered and doesn not look the same as expected or made. Link debugger can be your life saver at this point.
