Problem with old namespace in WSDL file

I have a problem with my WSDL file. My scenario is SOAP to IDOC.

Originally the ESB data types were configured under namespace urn:test1:xxx for development purposes. When it came time to implement and test, we copied the data types from the old name space to a new namespace http://company.com:interface.

After the new objects were created, all the old test objects were deleted, including the old namespace definition. Now when I generate the WSDL file, the top part of the WSDL file looks correct, but toward the bottom, there are references to the old namespace.

Does anyone know why these reference are appearing, and is there any way to correct this without deleting all my objects and rebuilding everything?

Thanks in advance for any help. Will award points for help.
