Hi anonymous user,
Per my research, those five default properties retrieve the property value in user profile and always with the default display names.
Changing display name in user profile doesn't impact it in profile info web part.
If we tick the option "Show in the profile properties section of the user's profile page" for these default attributes, the web part will display duplicate attributes and values since it is hard-coded and unable to realized the issue.
In addition, the "Phone" attribute on the profile page uses the workphone value in the user profile , which is mapped to the telephoneNumber attribute in AD.
As a workaround, we suggest you avoid mixing with the default property in profile info web part or create a custom web part to show profile page.
