QTR-Quadtone RIP

Hi,
Having spent weeks getting to grips with QTR and making a profile I now 
have a number of test profiles which are not required.  I have deleted 
the actual profiles via " Curve Creation  -  File  -  Delete" but they 
are still listed in the Curve 1 list in "Curve Setup" on the QTR 
Interface and are becoming distracting.  Can someone advise me how to 
delete them from there?..Thanks
