Why does my cart-transfrom-app not change product to zero for internatonal order

Shopify Apps

I created a Shopify extension app for my company that changes the price of the Free Ring Sizing Kit to 0 when an eligible product is added to the cart. It works as intended, but the issue is that when you switch the country, it displays differently in the cart. It does display as free in the checkout, no matter the country, if that helps. I can not figure out why it displays differently, but I need to be shown as 0, no matter the country or currency.

How it should look:

My code:

  import type {
  CartTransformRunInput,
  CartTransformRunResult,
  Operation,
} from "../generated/api";

export function cartTransformRun(
  input: CartTransformRunInput
): CartTransformRunResult {
  const operations: Operation[] = [];

const TARGET_VARIANT_ID = "gid://shopify/ProductVariant/43178165534896";

let triggerQty = 0;

for (const line of input.cart.lines) {
  if (
    line.merchandise.__typename === "ProductVariant" &&
    line.merchandise.product.inAnyCollection
  ) {
    triggerQty += line.quantity;
  }
}

if (triggerQty === 0) return { operations: [] };

for (const line of input.cart.lines) {
  if (
    line.merchandise.__typename === "ProductVariant" &&
    line.merchandise.id === TARGET_VARIANT_ID
  ) {
    if (line.quantity <= (triggerQty + 1)) {
      operations.push({
        lineUpdate: {
          cartLineId: line.id,
          title: "Free Ring Sizing Kit (Free With Order)",
          price: {
            adjustment: {
              fixedPricePerUnit: {
                amount: "0.00",
              },
            },
          },
        },
      });
    }
  }
}

return { operations };
}

Sorry I uploaded the same image twice, this is what it looks like when you choose a different country:

Hey @hpayne,

Thanks for Bringing this Question to Shopify community.
In order to do the requested changes requires to do the custom code in your theme file.
Would you like to provide me the 4 digits collab code in the p/m so that I can take a look.
Waiting to hear back from you.
Thanks
