Any station that you want to activate the master valve needs to be flagged to do so.
To change the setting of each station, tap the gear icon next to the station name. If you are using the recently updated UI with the new home screen this can be done right on the home screen. Otherwise, you will find this in the “edit stations” page.
Hopefully this resolves the issue.
