Restore Upon Death Not working

I have a .json file but when i'm in server it doesn't show up in Permissions manager? When i die i only get rock and torch upon respawn.
This is my .json file, what am i doing wrong.

{
  "Give default items upon respawn if the players is having items restored":true,
  "Can drop active item on death":false,
  "Can drop backpack on death":false,
  "Don't restore items if player commited suicide":false,
  "Wipe stored data when the map wipes":false,
  "Purge expired user data after X amount of days":7,
  "Percentage of total items lost (Permission Name | Percentage (0 - 100))":{
    "restoreupondeath.default":{
      "Belt":100,
      "Wear":100,
      "Main":100
    },
    "restoreupondeath.beltonly":{
      "Belt":100,
      "Wear":100,
      "Main":100
    },
    "restoreupondeath.admin":{
      "Belt":100,
      "Wear":100,
      "Main":100
    }
  },
  "Version":{
    "Major":0,
    "Minor":6,
    "Patch":4
  }
}

Try running

o.reload PermissionsManager​

once the server is up then looking in permission manager.

You can use

o.plugins

to verify the plugin is actually loaded
