The checkout saves the window only for the first package, leaving the second without one.\n\nAs a result, the \"Go to payment\" button does not respond, no error message is displayed, and no request is sent to the checkout API. Although the UI shows a delivery window selected for both packages, only the first one is saved in the orderForm.\n\nThis affects carts where items are split into two packages, each with its own scheduled delivery option, such as items shipped from different warehouses or under different delivery conditions.\n\n## Simulation\n\n- Enable scheduled delivery for two SLAs/shipping methods.\n- Add two items to the cart - each one should receive different shipping methods.\n- Go to the page `#/shipping`.\n- Select the same scheduled delivery date and time for both packages.\n- Try to proceed to payment.\n\n\n**Expected result:** Shopper should be able to proceed to payment.\n\n**Actual result:** Shopper cannot proceed to payment.\n\n## Workaround\n\nSelect a different delivery window for the second package and then select the desired delivery window again."}
