When I receive notifications they're normal, but messages are completely empty. why is that?

Is that on a Wikimedia wiki, or a 3rd party wiki?

If Wikimedia: Can you tell us what happens when you click the "..."?

If 3rd party: I'm not familiar with a bug like that. More details about your setup might help someone to diagnose the problem.
