NPC merchants show all categories although only one is specified

Since in the other channel was no longer helped I create now times here an official Support Ticket here again the text:

 Hello, I have the problem when I assign a Human NPC ID and want to sell only weapons with this, this shows me still all categories, although I have given this NPC only the category weapons, does anyone have a solution here?

"NPC Shops (NPC ID - shop categories)": {
    "2701811712": {
      "Categories (Titles) [* - all]": [
        "Waffen"
      ]
    },
    "7654321": {
      "Categories (Titles) [* - all]": [
        "Weapon",
        "Ammunition"
      ]
    }
  },

Same here
