Background of the issue:
I am trying to configure WPML settings for displaying untranslated products on my WooCommerce site using WPML.
Symptoms:
The option 'use translation if available or fallback to default language' is grayed out and not selectable in WPML settings.
Questions:
How can I make the option 'use translation if available or fallback to default language' selectable in WPML settings?
Is there a specific requirement or setting that needs to be enabled to activate this option?
