[Resolvido] woocommerce billing field is empty

Background of the issue:
I'm trying to place an order with a German address on the WPML WooCommerce store super-stuhl.de. If the 'Billing Company' field is filled in, it should remain filled in after the order is placed. The link to the page where the problem can be seen: link oculto

Symptoms:
The 'Billing Company' field will be blank after the order is placed unless the total price of the order is zero (0).

Questions:
Why does the 'billing company' field remain empty for German orders?
Is there a setting in WPML that causes this behavior?
