Custom taxonomy – delete option missed

I’m using your “Capability Manager Enhanced” and just find out that when I use it for custom taxonomy it doesn’t have “Delete” options (no check-box) even for Admin.
Here is a code I use for taxonomy:

$args = array(
‘labels’ => $labels,
‘hierarchical’ => false,
‘public’ => true,
‘show_ui’ => true,
‘show_admin_column’ => true,
‘show_in_nav_menus’ => true,
‘show_tagcloud’ => false,
‘query_var’ => ‘books’,
‘rewrite’ => $rewrite,
‘capabilities’ => array(
‘manage_terms’ => ‘manage_books’,
‘edit_terms’ => ‘edit_books’,
‘delete_terms’ => ‘delete_books’,
‘assign_terms’ => ‘assign_books’
)
);

register_taxonomy(‘books’, array(‘book-title’, ‘publisher’, ‘author’, ‘artist’, ‘post’, ‘page’), $args);

Could you please tell me how I can fix it?

Thank you,
