ImpactLightSoftSound does not work

[Duion]

Currently there is a different default footstep variations, light, hard, metal etc, the problem is, that the ImpactLightSoftSound does not work somehow, it is "impactSoundId = "0";" in material editor, while the hard sound works, which is ID=1, I used only this so far, but I need both and more later.
