Forced Noise Reduction even if set to 1

I cannot use this software because it applies Noise Reduction even if I set the parameters to 1 so none is applied. The program just does not respect grain of the image and with NR to 1 blotches appear of the image where NR is applied and other where none is applied creating really horrid images specially when there are smooth surfaces like in the sky.

This is a major flaw of gigapixel and the reason I will have to stick to Adobe Photoshop resize.
I hope someday you will fix this and give us the option to NOT apply any kind of NR and really make a High Fidelity option that truly respects the original image.
