I can't figure out how to keep Pirate Coves working

I'm doing the mission where you have 4 pirate coves.
For the life of me I can't figure out the interface. I have 61k raid points and 3 idle coves. I can click on the tab for each cove, but it doesn't seem like you can assign a job to them individually.
If I queue up a bunch of jobs, coves will still remain idle. Occasionally one of them will take a job but it seems to be random.
Is there something I'm not getting about how to assign jobs to coves? Or do they have a cooldown period after completeing a mission?

I would wager to say that only one pirate cove is operational at one time, so building more than one what's ♥♥♥♥♥♥♥ you up.
But also this game is programmed by children with no experience, so take that in mind.

You can only have one raid active at a time. So even if you have 1000 pirate bases, they will only be able to go on raids one at a time. What you get by having more then one base is an increase in raid points. So there is less down time in-between raids.

Also i really recommend using the "On a Dead Man's Chest" work mode for this map.

There is a scenerio in the game that requires 4 pirate bays. Normally I would only have one (if any at all). I actually said that at the start of the original message.
That said, I have got all 4 working. First I let all the missions that were running finish.
Then I selected one of the pirate bays in the mission planner interface (selecting the first hook tab).
From that tab I selected a mission. UP in the queue you can see the mission starting. One the mission disappears, I move to the next tab and queue a mission. Again I wait until the pirates begin the mission. And repeat for the remaining bays.
Doing it this way by staggering the missions I was able to keep all 4 bays going at once.
One annoying thing is that, even if you rename the pirate bay using the details pane, that name is not used when you are in the missions pane.
From other posts it seems as the interface has always been confusing and seems not to work correctly. Thats to bad because I'm fairly happy with the game.
