This thread is resolved. Here is a description of the problem and solution.
Problem: Page layout is not retained when using Elementor editor.
Solution: Follow this procedure: 1. In WPML -> Settings -> Custom Fields Translation (Show system fields), set "_elementor_css" and "_elementor_data" to Copy.
2. In WPML -> Settings -> How to translate posts and pages, select "Use the Classic Translation Editor" as this is the recommended method when using page builders.
3. In Elementor -> Settings -> Advanced -> CSS Print Method, select "Internal Embedding"
This is the technical support forum for WPML - the multilingual WordPress plugin.
