我想在我的WordPress站点中自定义帖子类型。为此，我使用了register_post_type my中的方法functions.php, 但为什么我的管理页面中只显示一种自定义帖子类型？

代码如下所示：

function create_my_custom_posts() {
    register_post_type( \'career_post\', array(
        \'labels\' => array(
            \'name\' => __( \'Careers\' ),
            \'singular_name\' => __( \'Career\' ),
            \'add_new\' => __( \'Add New\' ),
            \'add_new_item\' => __( \'Add New Career\' ),
            \'new_item\' => __( \'New Career\' ),
            \'view_item\' => __( \'View Career\' ),
            \'search_items\' => __( \'Search Careers\' ),
            \'all_items\' => __( \'All Careers\' ),
            \'add_new_item\' => __( \'Add New Career\' ),
            \'not_found\' => __( \'No Openings Yet\' )
        ),
        \'description\' => \'job openings in uvionics tech\',
        \'public\' => true,
        \'has_archive\' => true,
        \'menu_position\' => 5
    ) );
    register_post_type( \'employees_comnts_post\', array(
        \'labels\' => array(
            \'name\' => __( \'Emps Comnts\' ),
            \'singular_name\' => __( \'Emp Comnt\' ),
            \'add_new\' => __( \'Add New\' ),
            \'add_new_item\' => __( \'Add New Comnt\' ),
            \'new_item\' => __( \'New Comnt\' ),
            \'view_item\' => __( \'View Comnt\' ),
            \'search_items\' => __( \'Search Comnts\' ),
            \'all_items\' => __( \'All Comnts\' ),
            \'add_new_item\' => __( \'Add New Comnt\' ),
            \'not_found\' => __( \'No Comnts Yet\' )
        ),
        \'description\' => \'Employees comments about life in company\',
        \'public\' => true,
        \'has_archive\' => true,
        \'menu_position\' => 5
    ) );
    flush_rewrite_rules( false );
}
add_action( \'init\', \'create_my_custom_posts\' );
