Disabled zones are still enabled

I have a zone that is disabled (has the `enabled` flag set to `false`), yet I still get the messages for entering/leaving the zone, and the zone still restricts me from doing all of the things I have restricted in the flags. So clearly, it's not disabled. I've included a screenshot of the in-game GUI to show that it is in fact disabled, as well as my data file.

{
  "definitions": [
    {
      "Name": "Airfield",
      "Radius": 150.0,
      "Radiation": 0.0,

      "LeaveMessage": "Returning to safety!\nPVP <color=#00FF00>[disabled]</color>\nRaiding <color=#00FF00>[disabled]</color>\nLooting <color=#ff0000>[ENABLED]</color>\nTeleportation <color=#00FF00>[enabled]</color>",
      "Permission": null,
      "EjectSpawns": null,
      "Enabled": false,
      "Flags": "AutoLights, NoTp, NoPlayerLoot, NoHeliTargeting, LootSelf"
    }
  ]
}

It has other problems to. unDestr and NoDecay are not working for me. 

this.  this is an issue.  only option is to remove the configuration for the zone.  even if disabled, users are still seeing enter/exit messages.
