Conflict with WPML

We are using WPML to translate pages and we are having some issues with pages that have a custom permalink.

We have English, French and Spanish on the site.

Original English page: https://www.internetsociety.org/events/ietf-meetings/ietf-100/
English page w/ custom permalink: https://www.internetsociety.org/events/ietf/ietf-100/

When I duplicate the page, it duplicates the ORIGINAL slug – greyed out – with the appropriate language parameter (ie /fr/events/ietf-meetings/ietf-100/). I edited the permalink to remove “-meetings” and when I go to the page in the browser, the url becomes /fr/fr/events/ietf/ietf-100/.

I removed the /fr from the permalink (as WPML adds that programmatically). Now, if you are viewing the English page and go to the language switcher, you can correctly access the French and Spanish pages.

HOWEVER, once you are on another language (FR or ES), the urls for the other translated language (not English) are incorrect and just redirect you the current language you are viewing. (https://www.internetsociety.org//fr/events/ietf/ietf-100/)

I commented on another open ticket regarding WPML – but it was a different issue than what we are experiencing.

WPML says that the plugin is not on their list of compatible plugins and they recommended that the authors of this plugin go here to sort out compatibility: https://wpml.org/documentation/theme-compatibility/go-global-program/
