Missing label on breadcrumb menu when using custom action in CRUDController

[webdevilopers]

I have created a custom show action (inspection_results) and route inside my ContractAdminController.

class ContractAdmin extends Admin
{
    protected function configureRoutes(RouteCollection $collection)
    {
        $collection
            ->remove('delete')
            ->remove('export')
        ;

        $collection->add('inspection_results', $this->getRouterIdParameter().'/inspection_results');
    }
}

Technically everything works fine so far!

The I recognized that my breadcrumb menu was missing the label for my Contract entity. Instead it was directely showing the menu label Ergebniszusammenstellung for my action:

Looking at the showAction of the CRUDController I add the setSubject method: https://github.com/sonata-project/SonataAdminBundle/blob/master/Controller/CRUDController.php#L843

Now the label for my Contract entity appears:

But as you can see now the label of the action Ergebniszusammenstellung is missing at the final position.

Is there another variable I have to pass to the template?

            return $this->render('AppBundle:ContractAdmin:inspection_results.html.twig', array(
                'action'                         => 'inspection_results',
//                'action'                         => 'show',
                'object'                         => $contract
            ));
