Okay, so it at least translates now. That explains a lot. I understand this better now. So the user profile translations are not stored as metadata, but as string translations. Those are not possible to access for searching ufnortunately. WPML stores the string translations within a separate database, which is not searchable by the plugin. I’m afraid I can’t suggest a custom code for that either, it would have to be implemented completely from top-down.
