Another 2 zones running at the same time.

I have a rainbird system that is from 2004 when the house was built. Up until last year, system ran all 6 stations flawlessly.
Now the problem I have is that station 1 always runs when all other stations are on. So when station two turns on, station 1 turns back on. I should note, that when each zone stops running, all zones, including the problematic one turn off, then it starts up again.

I have checked the valve and replaced it and still having this problem. I have not been digging, jacking with the wiring, or anything like that. Thoughts?

switch the wires on your controller - zone 1 becomes the last zone, and the last zone becomes zone 1

Maybe zone 1 is hooked up to the master/pump terminal valve terminal as well as the number 1 terminal.
