remove page from header section

I'm using a theme called vectors and I’m trying to remove my about page from my header (next to the logo)

I’m referencing this in the header but I can’t seem to remove the page.

<?php wp_nav_menu( array(‘container’ ?> false, ‘menu_class’ => ‘menu-nav-top’, ‘theme_location’ => ‘top-menu’ ) ); ?>

Code (markup):

I assume one of these will remove it but everything I try produces a php error.

Anyone have any ideas how I can remove this thing?
