The curve is probably not a true circle with a constant radius. Try adding a R dimension to the hole to verify you can make a Radius dimension, and pay attention to the symbol beside the cursor.
You may have to dimension that curve a different way if it's not circular. Or, modify the 3D Part and change the model to a true circular fillet.
