When using Lingua on a Collection resource and the system setting
lingua.form_customization is set to
yes, all standard fields (pagetitle, longtitle, etc.) disappear on language switch in the manager. Switching back to the default language does NOT bring back the fields.
I am aware of “just turn the collection resource into a normal document, edit the fields and make the resource a collection again” workaround. But that is not practicable for my editors and contradicts the concept of form customization imho.
How can this be fixed?
