我无法将分类添加到自定义帖子类型。但对于相同的代码，如果我添加“post”或“page”，它会显示得很好。我无法指出问题所在。

这是代码。

注册自定义职位类型-工作正常

register\\u taxonomy（$键，\'SH\\u job\\u listings\'，$值）如果我用帖子或页面替换“SH\\u job\\u listings”，效果很好，但不适用于我创建的自定义帖子类型。

class SH_job_post_class{

    public function  __construct(){
        $this->register_job_Listings();
        $this->add_taxonomies();

    }

    public function register_job_Listings(){
        $args = array(
            \'labels\' => array(
                \'name\' => \'Job Listings\',
                \'singular_name\' => \'job Listing\',
