This thread is resolved. Here is a description of the problem and solution.
Problem: I cannot make my translated homepage content full width to match the original language.
Solution: The custom field ocean_post_layout was set to Not Translate. I changed it to Copy in WPML -> Settings and then updated the homepage. Now both languages are full width. This was a field that was coming from the theme OceanWP, and not from Elementor.
This is the technical support forum for WPML - the multilingual WordPress plugin.
