“Add to Cart” and “Related Products” not translating with Elementor

Hi there,

Thank you in advance for any assistance.

We have a site using Elementor and WooCommerce. We translated the Single Product page, and for some reason the text on the “Add to Cart” button and title for “Related Products” will not translate properly.

The first issue was that these items were just not translating to Chinese on the Chinese version of the page.

I contacted Elementor support, and they advised to edit the Elementor Single Product Page Template, which worked fine and solved the issue on the Chinese version.

However, now the English version is missing the Add to Cart button altogether, and the Related Products text appears in Chinese. The settings configuration seems fine. Elementor has advised to contact your support. They said that if you need help from them, you can open an issue on their Github page:

Do you have any idea what can be the problem?

Thank you again for any help!
