GI VFB channel problem

[JoeBold]

I wish to render the Gi as a seperate pass from my lights. But when I use the GI or RawGI pass from the VFB channels, it seems as if my lights affect the GI Pass. I can a giant highlight in the GI pass when the light is there and no highlight when the light is not there. I am using default settings. Is there no way to seperate the two? Why does this happen? Thank you.
