VrayLighting and VrayGlobalIllumination not matching VrayTotalLighting when using EnvironmentFog with scattergGI

[nballiett]

When I add the lighting and GI render elements together they do not give me the same result as totallighting, and ultimately I cannot recreate the beauty from render elements because of this even with properly adding in the atmosphere element.

Am I missing something really obvious? Or is this a bug?
Using Vray Next Update 3.2 in 3dsMax 2018.

I have attached two images showing the difference between the lighting/GI composite and totallighting here:

I have found its directly related to the amount of scatter bounces in the environmentfog. The additional GI those provide as they increase are not reflected in any of the render elements in back to beauty.
