Try entering a lower value as requested, if the DC R is actually higher it will end up with a corresponding dR value during the fit. If the curve fit is good afterwards there shouldn't be anything to worry about.
I was hoping you might share what the result was, the information provided so far doesn't really give any clues. Best would be to post the measurements themselves (attach the mdat file).
The phase of the measurements looks very strange, that is why the parameter fit is not working. Can you please make a measurement of a resistor in place of the drive unit, with the sweep range set to 0 Hz to 20 kHz, single sweep, and post that mdat?
