My account Edit Billing address doesn't save changes in Woocommerce

Question

I have a standard Woocommerc account. When I go to Edit Billing Address and edit some field and save it to my-account/edit-address/, the information remains the same when I reboot. Although if I enter a new value and save it, then when my-account/edit-address/billing/ is rebooted, this value will be saved. It disappears when you go to another page. What could be the problem?

<?php
/**
 * Edit address form
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/myaccount/form-edit-address.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 7.0.1
