Reappearance time not changing

Hello,

I changed the copter reappearance time but in games nothing changes:

Do you have a solution ?

{
  "AssetPrefab": "assets/content/vehicles/minicopter/minicopter.entity.prefab",
  "CanSpawnBuildingBlocked": false,
  "MaxSpawnDistance": 50.0,
  "NoMiniRespawn": true,
  "PermissionCooldowns": {
  "spawnmini.tier1": 1800.0,
  "spawnmini.tier2": 1800.0,
  "spawnmini.tier3": 1800.0
  },
  "SpawnHealth": 750.0
}
Have you assigned 1 of the spawnmini.tier permissions to a group/user?
no i am not doing that, or i have to add the spawnmini.tier authorization and how? Sorry I'm a little lost
you want to grant your users a tier depending on what cooldown you want them to have the command is oxide.grant user/group name permission
