Plugin Config Issue

No matter how many times i edit the config when i restart the server the config is getting reset.
and the recycler speed is vanilla. any help would be appreciated

hello Raul i have edited the config and restarted server which makes the config reset to default one, can you test it out once

{
  "Prefix": "Portable Recycler",
  "OpenCommand": "recycler",
  "PlayOpenEffect": true,
  "ChatIconSteamId": 76561198866865300,

    "CanUseRecyclerWhileRaidBlocked": false
  },
  "Phrases": {
    "CooledDown": "You're in cooldown.\n<size=12><color=orange>{0}</color> seconds left.</size>",
    "BuildingBlocked": "You're building-blocked.",
    "CombatBlocked": "You're combat-blocked.",
    "RaidBlocked": "You're raid-blocked.",
    "CloseClear": "Your <color=orange>Portable Recycler</color> emptied as you cannot store items inside of it."
  },
  "GroupCooldowns": {
    "default": 10.0
  },
  "GroupRate": {
    "default": 1.0
  },

}

I fixed it for now . as it is changing to default values i have edited .cs default values to my values. @Raul-Sorin Sorban
