Cut Opening components not rendering

I´ve changed Vray for sketchup from 3.6 to 5.2. Since the update the cut opening components and groups are not rendering anymore. The component itself is there but not the opening. I have to explode them or draw an extra face for the opening which is very unfortunate when editing or moving afterwards.
Any ideas? Thanks!

looks like i have to update then…

As a hobbyist you could just stick with SketchUp 2017 Make and the older version of Vray.

If it is not your hobby, why are you using Make?
