1H/15N hmqc

I have been attempting to set up a 1H/15N hmqc on a
DRX-400 running xwinnmr 2.0. I did it by calling in
the standard Bruker parameters for a 1H/13C hmqc and
then using edasp to change the nucleus for the second
dimension to 15N. The experiment worked but I ran
into problems when I tried to calibrate the chemical
shift scale for the 15N dimension. The SF value for
the 15N dimension always sets itself back to 100MHz
(the 13C frequency) even if I go into edp and explicitly
set it 40.5MHz(the 15N frequency).
Does anyone know how to work around this problem?
