API Creating Duplicate Attribute Terms with New Products

I have created multiple products via the REST API with attributes. However, instead of using existing matching terms, I know have a bunch of Attribute Terms with the same name… Any idea why this would happen?
My JSON data:

{
  "create": [
    {
      "name": "Product 1",
      "attributes": [
        {
          "id": 11,
          "name": "Classe de l'arme",
          "position": 0,
          "visible": true,
          "variation": false,
          "options": [
            "Non restreint"
          ]
        }
      ]
    },
    {
      "name":"Product 2",
      "attributes": [
        {
          "id": 11,
          "name": "Classe de l'arme",
          "position": 0,
          "visible": true,
          "variation": false,
          "options": [
            "Restreint"
          ]
        }
      ]
    }
  ]
}
