Wordpress Meta Box Plugin Specifying Page/Post

Understanding Meta Box (wordpress plugin). I'm trying to create meta boxes for specific pages/posts. I have created 2 meta boxes with a simple text field in them. I want one meta box to be for page/post id # 4 and another to be for page/post id # 22 I have the following code producing the meta boxes in the admin, however i can only get them to show on page/post id # 4. I want one to only show for page/post id #4 and another to only show on page/post id #22

Little help would be greatly appreciated. here is my code so far which i have placed in the functions.php file.

add_filter( 'rwmb_meta_boxes', 'KNMS_register_meta_boxes' );
/**
 * Register meta boxes
 * @param $meta_boxes
 * @return array
 */
function KNMS_register_meta_boxes( $meta_boxes )
{
    // Check before register meta boxes
    if ( ! rw_maybe_include() )
    {
        return $meta_boxes;
    }
    // Register meta boxes
    // @see http://ift.tt/1RM9MOE
    $prefix       = 'rw_';
    $meta_boxes[0] = array(
        'id'         => 'any_id1',
        'title'      => __( 'Meta Box For POST ID 4', 'knms' ),
        'post_types' => 'page',
        'fields'     => array(
            array(
                'name' => __( 'My Field For POST ID 4', 'knms' ),
                'id'   => "{$prefix}title1",
                'type' => 'text',

            ),



        ),


    );
    $meta_boxes[1] = array(
        'id'         => 'any_id2',
        'title'      => __( 'META BOX FOR POST ID 22', 'knms' ),
        'post_types' => 'page',
        'fields'     => array(
            array(
                'name' => __( 'My Field For POST ID 22', 'knms' ),
                'id'   => "{$prefix}title2",
                'type' => 'text',

            ),



        ),


    );
    return $meta_boxes;
}
/**
 * Check if meta boxes is included
 *
 * @return bool
 */
function rw_maybe_include()
{
    // Always include in the frontend to make helper function work
    if ( ! is_admin() )
        return true;
    // Always include for ajax
    if ( defined( 'DOING_AJAX' ) && DOING_AJAX )
        return true;
    // Check for post IDs
    $checked_post_IDs = array( 4 );
    if ( isset( $_GET['post'] ) )
        $post_id = intval( $_GET['post'] );
    elseif ( isset( $_POST['post_ID'] ) )
        $post_id = intval( $_POST['post_ID'] );
    else
        $post_id = false;
    $post_id = (int) $post_id;
    if ( in_array( $post_id, $checked_post_IDs ) )
        return true;
    // Check for page template
    $checked_templates = array( 'full-width.php', 'sidebar-page.php' );
    $template = get_post_meta( $post_id, '_wp_page_template', true );
    if ( in_array( $template, $checked_templates ) )
        return true;
    // If no condition matched
    return false;
}
