Custom Post Type Archive Title Lowercase

Question

Is there any reason that my custom post type archive title is all lower-case even though 'name' is defined as sentence-case?

Here is the post type function I'm using:

function resources_post_type() {
$labels = array(
    'name'               => _x( 'Resources, Help & Support', 'post type general name' ),
    'singular_name'      => _x( 'Resource', 'post type singular name' ),
    'add_new'            => _x( 'Add New', 'resources' ),
    'add_new_item'       => __( 'Add New Resource' ),
    'edit_item'          => __( 'Edit Resource' ),
    'new_item'           => __( 'New Resource' ),
    'all_items'          => __( 'All Resources' ),
    'view_item'          => __( 'View Resource' ),
    'search_items'       => __( 'Search Resources' ),
    'not_found'          => __( 'No resources found' ),
    'not_found_in_trash' => __( 'No resources found in the Trash' ), 
    'parent_item_colon'  => '',
    'menu_name'          => 'Resources'
);
$args = array(
    'labels'        => $labels,
    'description'   => 'Holds our resources and resource specific data',
    'public' => true,
    'show_ui' => true,
    'show_in_menu' => true,
    'query_var' => true,
    'menu_position' => 5,
    'has_archive'   => true,
    'rewrite' => array( 'slug' => 'resources' ),
    'supports' => array(
        'title',
        'editor',
        'author',
        'thumbnail',
        'excerpt'
    )
);
register_post_type( 'resources', $args );   
add_action('admin_init', 'flush_rewrite_rules');

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