Not creating weapon attachments

Hello,

I tried to give my bot a MP5 with Laser and Holo. It creates the MP5 at combat situation, but without the attachments. Partial config:

      "Items for fights": {
        "Enable random order instead of priority?": false,
        "Use ammo?": false,
        "List of items (in priority order)": [
          {
            "Allow to create item if it is not in inventory?": true,
            "Allow to give item when respawning?": false,
            "Item": {
              "Item shortname or ID": "smg.mp5",
              "Item skin": 0,
              "Attachments": [
                {
                  "Item shortname or ID": "weapon.mod.lasersight",
                  "Item skin": 0,
                  "Attachments": []
                },
                {
                  "Item shortname or ID": "weapon.mod.holosight",
                  "Item skin": 0,
                  "Attachments": []
                }
              ]
            }
          },
          {
            "Allow to create item if it is not in inventory?": true,
            "Allow to give item when respawning?": false,
            "Item": {
              "Item shortname or ID": "bow.hunting",
              "Item skin": 0,
              "Attachments": []
            }
          }
        ],
