WP Custom Menu Widget not showing headers?

Hi

I’ve just installed a new version of WP and when I’ve gone to add a custom menu for some reason the header is only showing as completely normal text rather than the <h> tag that it should?

I have checkout in the code and it just not there. I’ve looking in default-widgets.php at the relevant bit, I think atleast which I’ve included below,

class WP_Nav_Menu_Widget extends WP_Widget {

function __construct() {
$widget_ops = array( ‘description’ => __(‘Use this widget to add one of your custom menus as a widget.’) );
parent::__construct( ‘nav_menu’, __(‘Custom Menu’), $widget_ops );
}

function widget($args, $instance) {
// Get menu
$nav_menu = ! empty( $instance[‘nav_menu’] ) ? wp_get_nav_menu_object( $instance[‘nav_menu’] ) : false;

if ( !$nav_menu )
return;

$instance[‘title’] = apply_filters( ‘widget_title’, empty( $instance[‘title’] ) ? ” : $instance[‘title’], $instance, $this->id_base );

echo $args[‘before_widget’];

if ( !empty($instance[‘title’]) )
echo $args[‘before_title’] . $instance[‘title’] . $args[‘after_title’];

I would really appreciate some guidance here.
