Hello there,

Welcome to WPML support. I'd be assisting you further on this issue.

We recently released new versions of WPML plugins with fixes and improvements so could you please update the plugin to the latest version and let me know if this helps?

NOTE:

+ Make a backup (both files and database) for your site before updating/proceeding anything (Always a good practice!). You can use a plugin for this if you like. I often use the Duplicator plugin for this purpose. See: http://wordpress.org/plugins/duplicator/

Look forward to your reply.

Thanks
