doser 2 slave 3 pump the number 2 pump will not stop running

Having an issues with slave dosers I have a number of them:) I thought it was just one slave doser 2 where the 2nd pump would stay running all the time.
But I just hooked up a Gen 1 doser and as soon as I connect power to the doser the 2nd pump starts running too. I have a Doser 2.1 also but it doesn't do this problem.
When I remove the pab cable from the doser 2 the 2nd pump stops running.
When I remove the s cable from the gen 1 doser the 2nd pump stops running.

Nothing is set up on either pump in the Profilux 3.1ex

Some how the profilux is sending out the signal to do this. How do I reset the Profilux to stop this from happening?

Porbably "Pump reacts to" is set to "Switch channel" in the pump settings.
