Knowledge Locale Issue

Summary:

Hi everyone,

I’m trying to change the default locale from the English - United States to English - Canada, but I’m getting the following error:
Some knowledge administration objects, such as content type name, content field name, etc. have not been translated to this locale. Translate them before setting this locale as the new default locale. See the documentation for details.

Has anyone encountered this issue before?

I’d like to understand which knowledge administration objects need to be translated before I can disable the English - United States locale, and whether there is a recommended way to identify the untranslated objects.
