If you add or remove any additional attributes from the export file (see screenshots) then you need to re-initialize the exporter by performing the "Reset initialization data". Otherwise new or removed attributes do not show up properly on the list of "File header names override rules" setting.

Remember to wait approx 10 minutes before the exporter will be re-initialized again.


If you make other changes in the exporter, then it is sufficient to "Clean generated data" and wait until the exporter generates new files.
