Background of the issue:
I am trying to create a new order from the WooCommerce order page. When I add an item to the order with the status 'pending payment', I can add the item initially. However, when I click update or recalculate tax, the added items get removed. I found that the plugin causing this issue is 'WooCommerce Multilingual & Multicurrency'. When I disable it, I am able to add the item and update it too.
Symptoms:
Added items to an order are removed when updating or recalculating tax if the 'WooCommerce Multilingual & Multicurrency' plugin is enabled.
Questions:
How can I fix the issue where items get removed when updating an order with 'WooCommerce Multilingual & Multicurrency' enabled?
