Problem With Setting Motion Zone

Hi,I have two Stick Up cameras, both are being used as outdoor, both are plugged in, all settings should be the same with one another.On one camera I am able to set the motion zone over the whole area the camera can see. However on another camera, I can only set the motion zone on the lower two-thirds of what the camera sees. How do I fix this or what could be the issue? It looks like the screen of the problematic camera is moved upwards off the screen so I can't move the zone nodes beyond that. However, the other camera the screen sits fine.
