All page's end up in the menu

Hello,

When i add a page and don’t parent it with another page it ends up in my menu , even when i delete it in the menu section of wordpress its still visible on the site.

I think it has something to do with my php tag to call the wordpress nav menu ,

<ul>
<li><a href="<?php bloginfo('url'); ?>">Home</a></li>
				<?php wp_list_pages('sort_column=menu_order&title_li='); ?>
			</ul>
