We have used the wrong country for a working holiday maker and lodged a payrun through STP. We then corrected this and now can't lodge with the ATO.

After changing the country of origin for a Working Holiday Maker (WHM) we now get a validation error and can't proceed to lodge the next payrun.  The error says it is a Duplicate Income Stream Type with the stream type being WHM.  
I am a bit out of options - any suggestions?
