[Résolu] Issue with class update in variable product

Background of the issue:
I am add shipping classes to my English variable products, but the class isn't added to the Spanish variable product. I attempted to update from the Translation Dashboard, but it doesn't add the class to the Spanish version either.

Symptoms:
The shipping class is not being added to the Spanish version of the variable product. I expected the Spanish variable products to have the shipping class, but it is not working.

Questions:
Why isn't the shipping class being added to the Spanish variable product?
How can I ensure the shipping class is applied to the Spanish version?
