Custom taxonomy not refreshing page on add

Question

I have created a custom taxonomy for use with WP Job Manager. The taxonomy shows up, however when I type in my tag and click the "add new job title" button nothing seems to happen. If I click refresh I can see that in fact the tag has been added.

I think my question is similar to this one and this one. However I can not be sure because I am not entirely sure.

This is the the code:

// Register Custom Taxonomy
function ikana_jobtitle() {

       $labels = array(
            'name'                       => _x( 'Job Titles', 'Taxonomy General Name', 'text_domain' ),
            'singular_name'              => _x( 'Job Title', 'Taxonomy Singular Name', 'text_domain' ),
            'menu_name'                  => __( 'Job Titles', 'text_domain' ),
            'all_items'                  => __( 'All Job titles', 'text_domain' ),
            'parent_item'                => __( 'Parent Job titles', 'text_domain' ),
            'parent_item_colon'          => __( 'Parent Job:', 'text_domain' ),
            'new_item_name'              => __( 'New Job Title', 'text_domain' ),
            'add_new_item'               => __( 'Add New Job Title', 'text_domain' ),
            'edit_item'                  => __( 'Edit Job Title', 'text_domain' ),
            'update_item'                => __( 'Update Job Title', 'text_domain' ),
            'view_item'                  => __( 'View Job Title', 'text_domain' ),
            'separate_items_with_commas' => __( 'Separate titles with commas', 'text_domain' ),
            'add_or_remove_items'        => __( 'Add or remove titles', 'text_domain' ),
            'choose_from_most_used'      => __( 'Choose from the most used Job Titles', 'text_domain' ),
            'popular_items'              => __( 'Popular Job Titles', 'text_domain' ),
            'search_items'               => __( 'Search Job Titles', 'text_domain' ),
            'not_found'                  => __( 'Not Found', 'text_domain' ),
    );
    $args = array(
            'labels'                     => $labels,
            'hierarchical'               => false,
            'public'                     => true,
            'show_ui'                    => true,
            'show_admin_column'          => true,
            'show_in_nav_menus'          => true,
            'show_tagcloud'              => true,
    );
    register_taxonomy( 'jobtitle', array( 'post', ' job_listing', ' resume'     ), $args );

}
add_action( 'init', 'ikana_jobtitle', 0 );
