Lose some rendering options when going back to Rhino 6

I was playing around with materials in the WIP render, and when I returned to Rhino 6, I lost the Reflectivity and Clarity sliders for Plastics. Tried restarting Rhino and rebooting, but still nothing. Any suggestions? Thanks.

Edit: I see the Floating Editor still works, so I’ll stick with that until someone had a remedy.

if you create a material from scratch in V7 as opposed to opening a model that was back saved from v7, do you get the same result?

I created a new model in V6 and still get the same result.
