It may be data damage, as AlcaeusF suspects. Try editing the customer from the customer center (maybe add something to the notes or something) and then save it.  That may rewrite it and fix the problem. 

Be aware though that "name" also includes some aspects of the payment information like the terms. So if you are changing the terms for instance it will see that and ask if it is one time or permanent. If you say permanent it writes the change back to the customer record (where you can edit it as described above).
