4 of 5 stations turn on when I pressurize the system and won't turn off

Last fall everything was working perfectly. I had a company winterize my system. When I pressurize my system now, stations 2-5 turn on and remain on until I turn off the water supply. Station 1 will come on only if I turn it on at the control panel (normal function). I went to Home Depot, and they told me it was the sylinoids, so I replaced all 5 and wired them exactly the way they were, since the winterization did not rewire my system, and the same problem persists. What am I missing?

you might be missing that the zone valves were left mechanically 'open' after winterizing and they need to be returned to normal operating condition

How do you close a zone valve?
