You need to add sharpening and the rest will turn on. currently you have sharpening at 0
That does not bring the slider up. This is a tool I use weekly and have never had this problem until the 5.6 update.
with sharpening at 0 there is nothing for the other sliders to do. you have to move the Amount slider in order for the rest to become active. Ive tested this and this is normal operation.
