Cyclops with the power station 100 with a zmacs

So I have a cyclops with the power station and a zmacs I have 4 amps plugged into the zmacs do I have to unplug one of the amps out of the zmacs to use a modeler? I ask because the way it is now I’ve got one unplugged from the zmacs with no modeler plugged in to the zmacs and when playing threw the modeler with the cyclops with the power station 100 as a power amp it’s like it own rig not hooked up three the power station 100 I can switch cabs. But I switch amps it doesn’t matter because the cyclops switch has it at preamp. So do I need to unplug and amp from the zmacs or can I leave the 4th amp plugged in because the zmacs with the power station in power amp mode is acting like a 5th amp. Just making sure things are correct. Any help would be appreciated
