Problem:
The client was experiencing an error message indicating an undefined property related to WooCommerce and PayPal payment gateways.

Solution:
1. We acknowledged the issue and confirmed that our development team was able to reproduce it. The problem was specifically occurring when using the "WooCommerce Checkout Add-Ons" plugin alongside the PayPal plugin.
2. We informed the client that an Errata had been published for this issue, which can be found here: https://wpml.org/errata/woocommerce-checkout-add-ons-and-woocommerce-paypal-payments-fees-not-added-to-paypal-in-multicurrency-setup/
3. We released an update for WooCommerce Multilingual (version 5.3.5) that should resolve the issue. We advised the client to update the plugin to the latest version. If the update was not visible in the Plugin dashboard, we provided instructions to download the latest version from the WPML account downloads page: https://wpml.org/account/downloads/
