Strange routing behavior...

Hello,

I'm new to phalcon and I'm asking myself if this behavior is "usual" - to me it looks like a bug:

/**
 * Registering a router
 */
$di['router'] = function() {

    $router = new Router();

    $router->setDefaultModule("frontend");
    $router->setDefaultNamespace("Myspace\Frontend\Controllers");
    $router->addGet("/api1/:action", array(
        'module' => 'frontend',
        'controller' => 'api',
        'action' => 1
    ));
    $router->addGet('/', array(
        'module' => 'frontend',
        'controller' => 'index',
        'action' => 'index'
    ));
    return $router;
};

When the first route is called with correct parameters, I receive the following error mesesage:

• Myspace\Frontend\Controllers\Api1Controller handler class cannot be loaded

Which is correct, because I expect "ApiController" to be loaded instead of "Api1Controller"(see documentation: https://docs.phalcon.io/en/latest/reference/routing.html#parameters-with-names ). Am I missing something? Can't believe routing is faulty at this level.
