[Cerrado] language box missing product edit wp

Background of the issue:
I am experiencing an issue with WPML on my site enlace oculto. I am trying to edit WooCommerce products, but the language meta box is missing. I am using the Minimog theme, and my WPML version is fully updated. WooCommerce and WC Multilingual are installed and active. I have tried both 'Translate Everything Automatically' and 'Translate Some' modes. The product content is written in Danish, but WPML treats it as English.

Symptoms:
The language meta box is missing on WooCommerce product edit pages, but it appears on other post types like Pages and Posts.

Questions:
Why is the language meta box missing on WooCommerce product edit pages?
How can I correct the language setting for product content that is written in Danish but treated as English by WPML?
