Actor still receiving messages from mediator after termination

[pedroyan]

Akka.Net Version: 1.3.9
Platform: Windows 10 - Microsoft Service Fabric

According to the docs:

Actors are automatically removed from the registry when they are terminated, or you can explicitly remove entries with DistributedPubSubMediator.Unsubscribe.

But after terminating the subscriber actor, messages published to the subscribed topic keep being redirected to the subscriber's dead letters.
