Myth-Auth Role filter parameter issues

Hi,
i am using myth-auth in My application that have both frontend and backend users.

backend user groups:  owner, admin, customer_support
frontend user groups:  customer

i want all the loggedIn backend users to pass through the below filter.

in app/Config/Filters when i use filter parameters like below

Code:

public filters = [
    'role:owner,admin,customer_support' => ['before' => ['admin/*']],
];

am getting  the following error.

role:owner,admin,customer_support filter must have a matching alias defined.

So how can i achieve this?

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?
