How do I make the backpack appear next to the corpse when a user dies?

{
  "Drop on Death (true/false)": true,
  "Erase on Death (true/false)": true,
  "Use Blacklist (true/false)": false,
  "Clear Backpacks on Map-Wipe (true/false)": false,
  "Only Save Backpacks on Server-Save (true/false)": true,
  "Blacklisted Items (Item Shortnames)": [
    "autoturret",
    "lmg.m249"
  ],
  "GUI Button": {
    "Image": "https://i.imgur.com/CyF0QNV.png",
    "Background color (RGBA format)": "1 0.96 0.88 0.15",
    "GUI Button Position": {
      "Anchors Min": "0.5 0.0",
      "Anchors Max": "0.5 0.0",
      "Offsets Min": "185 18",
      "Offsets Max": "245 78"
    }
  },
  "Backpack Size (1-7 Rows)": 1
}

Is it not already dropping on death with that config? Setting Drop on Death to true is correct, but Erase on Death should be set to false. Not sure off the top of my head what happens when both are true but you are only supposed to set one of them to true since one will take precedence.
