Two Zones coming on at once

I have a Gen 1 that has worked flawlessley. Recently we had new valves installed, the wiring is correct, when manually operated, everything is fine. When I test via the app, there is one zone that gets turned on when I do a quick run on 2 zones on the app. One of them (on the app is correct, the other is another zone entirely. Again, the wiring seems to be correct, scratching my head . Thanks in advance…
