Salesforce Integrations - Contacts not Imported

Hello, I followed all the steps listed in this page: https://knowledgebase.constantcontact.com/articles/KnowledgeBase/43703-Connect-your-Constant-Contact-account-with-Salesforce?lang=en_US Ran the import (in this case, I ran it for "all contacts"), import status says "Success", but the list I created for this purpose is empty. Help?
