Menu problem in archive page

Hi,

I added this code in my functions.php to show CPT posts in my archive template:

function add_custom_types_archive( $query ) {
if( is_category() || is_tag() && empty( $query->query_vars['suppress_filters'] ) ) {
$query->set( 'post_type', array(
 'post', 'destination'
            ));
      return $query;
    }
}
add_filter( 'pre_get_posts', 'add_custom_types_archive' );

I have a CPT by name of “destination” with taxonomy of categories and tags. When I hit on one of the category pages, it shows the CPT posts from that specific category, but the menu disappears. When I click on the logo and go to home page, the menu comes back. I can’t figure out what’s causing the menu to disappear. When I compare the code from home page and archive in Firebug, I see that in the archive/category page, the navbar is not being outputted at all.
