I've got a problem with the first mission in the campaign

I'm playing for the Russians. Got the spec ops of, identified the patrol vessels, the ssn's, the ships in harbor. Got the message to stop the ships from leaving, shot a Sovremmny, got a positive radio message about it. And now the problem, in the status screen is the "stop ships from leaving"-order twice and i've got no idea how to fullfill it the second time. It's definitly not shooting the ssn's, tried that already. The other ships have stopped.
Any idea?
