Myth-Auth Role filter parameter issues

I'd suggest having everything redirect to your custom filter code, which is responsible for the role check, and handles each accordingly... it would probably simply return for this "super-user" group, and redirect other users to a "have a nice life" page.

I have another issue also;

$routes->group('admin', ['filter' => 'login'], function($routes){

        $routes->group('catalog', [ 'namespace' => 'Modules\Catalog\Controllers' ], function($routes){

              $routes->group('products', function($routes){
                             $routes->add('/', 'Products::productList', ['as' => 'product-list' ]);
              });
       });
});

when am using route groups like this , the filter is not working on the top group. 
what may be the issue?
