Problem hiding metabox

Hi there,

I have got this plugin working for metaboxes I wish to show for a specific template but not for hiding. I cannot get metaboxes to hide. I am using the following setup, can you tell me what I am doing wrong as there aren't any examples of hiding on your website?

$meta_boxes[] = array(
    'id'       => 'page',
    'title'    => 'Page Details',
    'pages'    => array( 'page'),
    'context'  => 'normal',
    'priority' => 'low',
        'hide'  => array (
        'relation' => 'OR',
        'template' => array('page-templates/frontpage.php'),
    ),
