Still letting players place turrets

I have the below settings but players can still place turrets.... Are there any know mod conflicts? I don't have anything specifically related to turrets. 

{
  "Config": {
    "Admin Can Bypass Build Restrictions": true,
    "Disable All Turrets": true
  },
  "Limits": {
    "Individual Control": {
      "AutoTurret": {
        "Maximum": 0
      },
      "Flame Turret": {
        "Maximum": 0
      },
      "Sam Site Turret": {
        "Maximum": 0
      },
      "Shotgun Trap": {
        "Maximum": 0
      }
    }
  }
}

Still having this issue but I have mine set to 150. They can place past them. Any word on fixing this?
