Function Discount Not showing discount message in Checkout

[sanjar]

Here is my output: 

{
  "discounts": [
    {
      "message": "20% OFF VIP CUSTOMER",
      "targets": [
        {
          "productVariant": {
            "id": "gid://shopify/ProductVariant/XXXXX",
            "quantity": 2
          }
        }
      ],
      "value": {
        "percentage": {
          "value": 20
        }
      }
    }
  ],
  "discountApplicationStrategy": "ALL"
}

And in Checkout it only shows Discount Code, but not custom message.  Maybe there are some other pre-requisites I'm missing?

Is the combination selected for the special discount? Could it conflict with other discounts?
