I have faced the same issue but it will be resolved by code replaced as below:
function register_fashion() {
$labels = array(
'name' => 'AJ Fasions',
'singular_name' => 'AJ Fasion',
'menu_name' => 'AJ Fasions',
'name_admin_bar' => 'AJ Fasion',

'update_item' => 'Update Item',
'view_item' => 'View Item',
'view_items' => 'View Items',
'search_items' => 'Search Item',

);
$args = array(
'label' => 'AJ Fasion',
'description' => 'Post Type Description',
'labels' => $labels,
'supports' => array( 'title', 'editor', 'thumbnail', 'custom-fields' ),
'taxonomies' => array( 'fashion_category' ),
'hierarchical' => false,
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'menu_position' => 5,
'show_in_admin_bar' => true,
'show_in_nav_menus' => true,
'can_export' => true,
'has_archive' => true,
'exclude_from_search' => false,
'publicly_queryable' => true,
'capability_type' => 'post',
);
register_post_type( 'aj-fashion', $args );
}
add_action( 'init', 'register_fashion', 0 );
