Controlling multiple cameras on ATEM Televison HD8 ISO

I have multiple Blackmagic cameras connected to my HD8 ISO switcher. The issue is that when I select camera 1 on the board it controls all the cameras, and I have no control on camera 2, 3, 4, etc. when selected.
I need to be able to control each camera separately.
