Turning them off during game play via the Settings -> Game Preferences, does not write the setting to the Harpoon3.ini file where they are saved. Only the launcher is capable of doing that. Changes made via the Game Preferences menu are saved for the current session and then discarded once you finish playing. They also only apply from the time you change the settings, so it's not going to retrospectively fix the issue.
The best way of removing a Patrol station is to not allow it to be created in the first instance, so the settings provided via the ANW Launcher are critical to controlling your assets during game play.
I can't say I have a method for deleting a Formation Air Patrol, the issue has caused untold problems for me when rebuilding the Harpoon 2 stock scenarios for H3 ANW. A sure fire method would be to break your group up, detach all the units from the group and then reform it. This will reset all of the Formation Patrol Stations and allow you to reassign ships and or aircraft to the appropriate patrol stations. There is as far as I know no way of deleting a particular patrol zone and hence my remark about deselecting the Game Engine's ability to assign these by default.
Just to reiterate, Changes made via the Game Preferences menu option are enforced for that session only and are NOT saved to the Harpoon3.ini file. The H3 ANW Launcher is the only way to save changes to the INI file other than manually (not recommended, unless you really know what you're doing). Sorry that I can't help with the deletion issue, although I'm happy to stand corrected if somebody has a method that, can be employed to remove the requirement to break a group up to achieve your goal Chris. Hope that helps?
