I had trouble with this option in the beginning also. So I switched to the following commands once I found them:

/jamba-follow strobeon all - I put this in my invite team macro, but you can put it anywhere convenient for you.

/jamba-follow strobeoff all - This I put on my master's down arrow key which is the "move backward" button on slaves.

All I do is keep this on at all times unless I need to park my slaves or am using my tank/caster teams.
