Getting error message 'not implemented yet' when uploading test cases

A user is receiving the message 'not implemented yet' when trying to upload test cases with the zfj-importer-utility.  I set up a load the same way.  I received the same error when I tried uploading her spreadsheet.  I tried editing the spreadsheet, spelling the labels in the first row exactly as is shown in the importer.  No change.  I then tried adding the test cases with the add-in that we also have.  The test cases were able to load.  I have included the log.
