Hello

Ive been setting up my GUI Shop and noticed that every icon under "Commands" shows the same image. Also it doesnt update the prices that ive updated the items to under Commands.

Dont see anything in the logs to point me in the right direction. ive unloaded and removed the plugin and readded it one by one but still the same

You need to give it a shortname for custom command images to update you can put anything as the shortname as long as its all lowercase 

    "Tank": {
      "DisplayName": "Tank",
      "Shortname": "tank",
      "EnableBuy": true,
      "EnableSell": false,
      "Image": "https://assets.umod.org/images/icons/plugin/5b63be754b61e.jpg",
      "SellPrice": 1.0,
      "BuyPrice": 1.0,
      "BuyCooldown": 0,
      "SellCooldown": 0,
      "KitName": null,
      "Command": [
        "spawntank $player.id"
      ],
      "SkinId": 0
    },
