This thread is resolved. Here is a description of the problem and solution.
Problem: After migrating my site from Polylang my site is missing some content.
Solution: Follow the documentation at the documentation here: https://wpml.org/documentation/related-projects/migrate-polylang-wpml/.
In this case, the site was using a custom theme with many custom widgets. To resolve the issue may require custom programming on your theme developer's part. However, we can try one more thing.
Please create a separate widget in Appearance -> Widgets -> Footer 1 Column. Create one widget for English and one for Arabic. Then, in your Arabic widget, set the page widget to the Arabic page where you have created the menu. Please keep in mind that you will need to translate each menu as well as each page where these page widget/menus are created.
Be sure to set each widget to their respective language after they are created.
