Thank you for contacting WPML support. I'd be happy to assist you on this issue.

To debug this issue further, I would need to check your site settings once, for this I would need temporary access (wp-admin and ftp) to your site.

So could you please provide me with those details, you will find the needed fields for this below the comment area when you log in to leave your next reply.
