Issue with the WooCommerce Checkout

We are experiencing an issue with the WooCommerce checkout. Address autocomplete is working, but the unit or apartment number field is not being populated when an address is selected. The checkout works correctly on Windows. However, on Mac, after entering all details, including name, phone number, email address, and billing address, a shipping method appears to be selected by default. There are no visible errors on Mac. I tested this in Chrome, Safari, and Firefox. However, when placing the order, the checkout does not proceed. If we manually change the shipping method and select it again, the order goes through successfully.
