The store credit is applied multiple times during order placement.

Steps to reproduce:

  1. Create a customer and add store credit to the customer account.
  2. Add a simple product to the cart.
  3. Set shipping address and billing address for the cart.
  4. Check the cart’s grand_total.
  5. Apply store credit to the cart using the following GraphQL request:

mutation {
    input: { cart_id: "%cartId%" }
  ) {
    cart {
      prices {
        grand_total {
      applied_store_credit {
        applied_balance {
        current_balance {

Expected results:

The value of applied_store_credit is applied accurately, and cart totals are correctly reflected in the API response.

Actual results:

The value of applied_store_credit is applied twice, affecting both the cart and grand_total.
