WooCommerce Multilingual - Product Variations with Price Set to 0 Show as Out of Stock in Secondary Languages

Overview of the issue

When using WooCommerce with WooCommerce Multilingual, product variations with a price set to 0 (zero) in the original language may appear as out of stock in secondary languages.

Workaround

Our developers are currently investigating the root cause of the issue. In the meantime, you can use the following workaround:

1. Edit the product in the default language and go to the "Variations" tab.
2. For each variation that should be priced at 0, set the price explicitly as 0.00 (or 0,00 – depending on your store’s decimal separator).
3. Click "Update" to save changes.
