I am trying to create a custom post. Code is below. Everything seems to work except the post edit box and title box doesn’t show up. The custom status appear though. which is weird. am I missing something in this code?

add_filter('piklist_post_types', 'my_custom_posts');
function my_custom_posts() {

    $post_types['articles'] = array(
    'post_states' => true
    ,'labels' => piklist('post_type_labels', 'Articles')
    ,'title' => __('Articles')
    ,'public' => true
    ,'rewrite' => array(
      'slug' => 'articles'
    )
    ,'capability_type' => 'post'
    ,'edit_columns' => array(
     'title' => __('Article Title')
     ,'author' => __('Author')
   )
    ,'supports' => array(
      'author'
      ,'revisions'
    )
    ,'hide_meta_box' => array(
      'slug'
      ,'comments'
      ,'commentstatus'
    )
    ,'status' => array(
        'draft' => array(
          'label' => 'New'
        )
        ,'submittoeditor' => array(
          'label' => 'Submit to Editor'
        )
        ,'openforreview' => array(
          'label' => 'Open for Review'
        )
        ,'published' => array(
          'label' => 'Published'
        )
        ,'rejected' => array(
          'label' => 'Rejected'
        )
      )
  );
