Problem:
Product variations are not visible in some languages.

Solution:
Please make sure that the WooCommerce Multilingual plugin is installed.

WooCommerce Multilingual automatically creates and synchronizes product variations in all languages. After you create a variation in the default language, save the product (in the default language) and WooCommerce Multilingual will immediately create the same variations for all translations of the product.
