A couple of things you may want to check are:

1. Make sure the entity definition inside MetaDataDefinitions.xml is correct.
3. Verify the entries into the Channel Config.
2. If you have extended the Profile entity make sure that the changes you have made to the Profile Schema don't have any name mismatches. So open up Commerce Server Manager and make sure that the Profile Definition and the Data Object is named appropriately.
