Imported Notes linked but not visible under Contacts


I imported a list of Notes related to existing Contacts via the Import Wizard and I mapped the Related To Module and Related To ID parts along with the other fields. And when I view a list under Notes and click one I see the correct link to the Contact but when I view that Contact there is no note listed under History.

I did the exact same thing for Leads and Opportunities and Accounts and those worked as expected. The Notes are visible under each associated record within those modules.

Any idea why the Notes>Contacts is not working and how to fix it so I can see the associated Notes under History for a given record?
