Object Displays Translations in a Language Different from the Project or Object Default Language

If the object does not contain translations for either the project default language or the object default language, it must use the translations that it does have. The system treats those object translations as if they were in the project default language.

For example, the project's default language is English, the object's default language is French, and the object contains only French translations. If French is disabled from the project, the French translation is displayed but is be treated by the system as if it were English. The object's default language automatically changes to English.
