Navigation code

Using the following code in my navigation and am trying to get rid of duplicating menu items.

If a top level menu item is called “services” the on hover on the menu will show “services” as well. Can you tell me where this happens in the php and how to correct it?

$my_wp_query = new WP_Query();
 $all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));

 $top_level = false;

 if ( isset( $post->ID ) ) {
 	$current_id = $post->ID;
 	$top_level = true;
 	if ( $parent = array_reverse(get_post_ancestors($post->ID)) ) {
 		$current_id = $parent[0];
 		$top_level = false;
 	}
 } else {
 	$current_id = '';
 }

 $menu_name = 'primary';
 $has_children = false;
 $secondary_nav = false;

 if ( ( $locations = get_nav_menu_locations() ) && isset( $locations[ $menu_name ] ) ) {
		$menu = wp_get_nav_menu_object( $locations[ $menu_name ] );

		$menu_items = wp_get_nav_menu_items($menu->term_id);

		$menu_list = '<ul id="menu-' . $menu_name . '" class="nav pull-right">';

		foreach ( (array) $menu_items as $key => $menu_item ) {
		    $title = $menu_item->title;
		    $url = $menu_item->url;
		    $link_class = '';

		    if ( $menu_item->object_id == $current_id ) {
		    	$link_class .= 'current';
		    }

			$menu_list .= '<li class="' . $link_class . '"><a class="collapseToggle" data-target="#collapse-l1' . $key . '" href="' . $url . '">' . $title . ' <span class="glyphicon glyphicon-chevron-down visible-xs visible-sm"></span></a>';
			$menu_list .= '<ul id="collapse-l1' . $key . '" class="panel-collapse level-one">';
			$menu_list .= '<li class="' . $link_class . '"><a class="indent" href="' . $url . '">' . $title . '</a></li>';

			$children = get_pages( array(
				'parent' => $menu_item->object_id,
				'post_type' => 'page',
				'post_statue' => 'publish'
			) );

			foreach ( (array) $children as $key => $child ) {
					$link_class = '';
					if ( isset( $post->ID ) && $child->ID == $post->ID ) {
						$link_class .= 'current';
					}
					$children = get_pages( array(
						'parent' => $child->ID,
						'post_type' => 'page',
						'post_statue' => 'publish'
					) );

					if ($children) {
						$menu_list .= '<li><a class="collapseToggle" data-mobile="1" data-target="#collapse-l2' . $key . '" href="/' . get_page_uri( $child->ID ) . '">' . $child->post_title . ' <span class="glyphicon glyphicon-chevron-down visible-xs visible-sm"></span></a>';
						$menu_list .= '<ul id="collapse-l2' . $key . '" class="panel-collapse level-two">';
						$menu_list .= '<li class="visible-xs visible-sm ' . $link_class . '"><a href="/' . get_page_uri( $child->ID ) . '">' . $child->post_title . '</a></li>';

						foreach ( (array) $children as $child ) {
							$displayInMenus = get_field( "display_in_menus", $child->ID, true );
							if ( !isset( $displayInMenus ) ||  !$displayInMenus ) {
								$link_class = '';
								if ( isset( $post->ID ) && $child->ID == $post->ID ) {
									$link_class .= 'current';
								}
								$menu_list .= '<li><a class="' . $link_class . '" href="/' . get_page_uri( $child->ID ) . '">' . $child->post_title . '</a></li>';
							}
						}
						$menu_list .= '</ul>';
					} else {
						$menu_list .= '<li><a class="indent" href="/' . get_page_uri( $child->ID ) . '">' . $child->post_title . '</a>';
					}
					$menu_list .= '</li>';

			}

			$menu_list .= '</ul>';
			$menu_list .= '</li>';

		}
		$menu_list .= '</ul>';
 } else {
		$menu_list = '<ul><li>Menu "' . $menu_name . '" not defined.</li></ul>';
 }

 $primary_nav = $menu_list;
