Negative Drag on Airfoil

I am getting relatively accurate Lift measurements but my drag values are all negative for my airfoil.
I have tried a number of turbulence models and all give the negative drag. I have obtained some form of mesh independence by using the Adapt Gradient tools.
I think I might have a problem with my reference values? Does anyone know how I could change my coordinate system?
