Contact Name and Email colums mismatch

Contact Name and Email colums mismatch

All,
 
Having just finished installation of product 7.9 build 7908, we are having a problem whereby, the Contact Name is the source of the request but the email address on the same line is that of the previous requester i.e. the person who sent the earlier request.
 
This is confusing. Our installation is for evaluation purposes with intent to purchase. Please advise what we could be missing. See screenshot below - the name charles appearing for many requesters is a coincidence but the last names are different
