There is a documented problem with the hardness test in this kit. I believe the indicator is being bleached by high chlorine levels because if you add a drop or two of the thiosufate reagent from the total alkalinity test (the first reagent for that test) the hardness test develops the proper color. This test only seems to work properly if the chlorine is 3 ppm or less. Also this is NOT a calcium hardness test but a total (calcium and magnesium) hardness test so it really isn't that useful.
