[סגור] WooCommerce PDF Invoices issue wpml

Background of the issue:
I am trying to configure WooCommerce PDF Invoices on my site קישור נסתר to generate invoices in different languages using WPML. I am following the documentation at https://woocommerce.com/document/woocommerce-pdf-invoice-setup-and-customization/.
also the button cannot be translated because the page settings are not saved, only one language is saved
I attach the plugin documentation and screenshots

Symptoms:
I can't save the settings for each language so that the PDF generates information in different languages. There is a problem with saving the settings.

Questions:
Why can't I save the settings for each language in WooCommerce PDF Invoices?
Is the issue with the WPML plugin or the WooCommerce PDF Invoices plugin?
