Thank you for contacting WPML Support. Thanks for sharing the screenshot, It seems you are unable to translate the pages on your site. Can you please make sure to set the Pages post type to Translatable by following the below steps:
1. Go to the WPML >> Settings page.
2. Scroll down to the “Post Types Translation” section.
3. Set the Pages post type as “Translatable only show translated items” as you can see in the attached screenshot.
4. Clear all sorts of cache from your site/server/CDN and see if this resolves the issue.
