Product variations were missing in some product translations.

- Backup the site completely to prevent any issues.
- Going to WooCommerce -> WooCommerce Multilingual & Multicurrency page , then going to Attributes tab selecting the attribute and clicking on "Synchronize attributes and update product variations" button.
- Go to WooCommerce -> WooCommerce Multilingual & Multicurrency -> Status -> Troubleshooting then select "Fix translated variations relationships" and allow it to run completely.
