Incorrect Name being applied to email addresses

Somehow AdobeSign has associated an incorrect name with the email address of someone that needs to sign the document. How do I change the name associated with an email address? I never assigned the name and I don't know where it came from. The incorrect name is also being added to the document in blue by AdobeSign when the correct person signs the document-- that's the biggest problem. At the very least I need to keep AdobeSign from adding the incorrect name to the document.
