On the ATEM 4K switchers, the front panel control buttons only change the video source for the Aux outputs.
As others have advised you, to change the Program video output you will need to use the ATEM Software Control application (running on a computer) or some kind of hardware control surface.
It's only some of the newer video switchers like the ATEM Constellation models that have front panel buttons that can change the Program or Preview outputs.
