Fumefx render element not in Vray Next Frame Buffer

[DaFord]

I just updated to 3DS Max 2020, Vray Next 2.x, and FumeFX 5.
I am setting FumeFX Smoke as a render element in Vray Next, but it does not show in the Frame Buffer pulldown menu.

Is this associated with a problem with FumeFX or with Vray Next, or 3DS Max ?

Also, Vray crashes randomly on rendering FumeFX, I have had no problems with Tyflow or Phoenix.
The same fumefx scenes render in scanline without problem.
