Entry header showing in post header

For some reason when i put content on a page it is showing the entry header image in the post as well. Ive tried this css to fix it but it gets rid of the entire header image on the blog as well:

.entry-header {
display: none;
}

the page id is 59 and i inspected the page and it has the same html code as the actual header image of my website. It doesnt make any sense. Any idea how to stop it from happening?

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