Hello,
Thank you very much for choosing our theme and contacting us.
1. Please check your global page settings Theme Setting > General Layout > if you have set there a sidebar, translated page (created by default will inherit these settings)
2. Usually translated page is the mirror page of the source page. Please check the issue on some default theme. If you have the same on a default theme contact WPML support. If you have the issue only on our theme please deactivate all the plugins not related to the theme, except WPML and provide your site access and page with formatting without a translation so that we could test and check.
3. Navigate to string translation and apply search to insert your translation quicker and easier.
Best Regards
