This thread is resolved. Here is a description of the problem and solution.
Problem: I have translated the page using the WPML Translation Editor but the CSS is not copying over.
Solution: Please try the solution in the ticket below and see if that solves the issue: https://wpml.org/forums/topic/sync-the-css-from-wpbakery-plugin/
Also, another alternative would be for you to use the duplication method below (instead of using the "+" translation method): https://wpml.org/documentation/translating-your-contents/displaying-untranslated-content-on-pages-in-secondary-languages/using-content-duplication/
