Multiple sites on Forge using Redis queues

Hi, I have multiple sites on one Forge deployed server. On two of them I'm using queues to dispatch some tasks. I've noticed in the logfile that sometimes site A wants to run the tasks of site B. Of course this will result in an error. I think I misconfigured the queue in Laravel and/or Forge, but I cannot find any information on how to do it. I have a feeling that the "default" should be site specific.

This is my Forge setup (on both sites):

Connection: redis
Queue: default

This is the config/queue.php setup:

    'connections' => [

        'redis' => [
            'driver' => 'redis',
            'connection' => 'default',
            'queue' => 'default',
            'retry_after' => 90,
        ],

    ],

Hope someone can help me out!

I think the 'queue' on both configurations should be named uniquely. But since these sites are both live I just want to be sure.
