The theme you are using may have an option for different templates. Check what template the source page is using and then make sure the translated pages are using the same template. You can set this to automatically copy over by following the step below. (Or you can change the page template manually after downloading the translation.)
- Navigate to Lingotek -> Manage -> Custom Fields and look for the Custom Field Key of _wp_page_template. Set the action to “Copy”. Save Changes.
