Hello

It's a common way of how UNA works with Private content. You may see the same results if you'll create 'Me Only' posts, photos, etc.

Profile page (subpages) should show all content but depending on the 'relations' between Owner and Views the content will be visible (for example, privacy is set to Friends, Owner and Views are friends) or invisible (privacy is set to Me Only, etc).

Home page, module's home page (subpages) have only public listings. It means that they have items with Public visibility only. In this case you won't see cards with 'Private Content'.
