Valve not recognized

First time setup. The app doesn’t recognize that there is a new valve connected to zone 3. It previously recognized the old valve but it then zone 3 disappeared off the app once I put in the new valve. I can’t figure out how to get it back. Manual mode doesn’t work either.

@toddtatum - is the zone marked as disabled by chance? Select the option to show disabled zones and see if zone 3 shows up.
