double shader material not working

im trying to adjust settings in the double shader material and it seems like everything is being overridden by a matcap.

when i click on the ‘show used’ button, the matcap that is overriding everything shows up with the double shader.

is there a way to reset a material to it’s original settings? i just don’t want it to be pulling info from a matcap. the tri shader and the quad shader have the same issue.Capture.JPG
