1 or more zones coming on

I have 16 zones. The first three come on by themselves. When i go to turn the rest of them on the #3 zone comes on again so i have 2 zones coming on at once all the time. Is that a manifold issue cause the wiring has never changed.

If you have a master valve I'd say the number 3 valve needs repair.

Find the number 3 valve and disconnect one of the wires from the solenoid.
Now go back to the controller and turn on a station. Does number 3 still come on?
Yes = the valve's bad.
No = the wiring's crossed.
