Original Title: Contacts

If you are using iCloud to sync Contacts across device try disabling that and compare your results...

possible simply toggling off and back on may be the answer...

The resolve maybe Sign out of your Apple ID/Account /iCloud on the Mac and back in again and compare your results Sign in to or out of your Apple Account on Mac - Apple Support
