Its working in wp standard themes and some other third party themes like rehub and auros theme.
But when we activate your theme the design is only in elementor builder okay:

If we open the product detail page in frontend the design looks like this:

Do you never test the most important function of elementor with your theme? 🙁
Elementor is very well known for his option to build woocommerce detail pages.

Your sale support write me: it will works fine. But it doesent work okay. 🙁
