Hi,
Presmaster is a Master Control Mixer / Keyer Control Protocol and GVG Native Protocol is a Router Matrix Control Protocol. When an MC1 is connected to a NK Router, it acts as the Crosspoint controller, and automation should be using the Presmaster Driver in MC1 to control the system, and not directly controlling the NK crosspoint. If you directly switch the NK Router from automation, then MC1 will not track the status correctly.
