Vray 3.4: changing Vray render engine breaks all the saved rendering parameters

[bardo]

Hello,
probably I've found a bug...at least something strange.

I've installed today the new Vray 3.4 (for 3dsmax 2016).
I've opened a scene I've made last week with Vray 3.3, rendered and it was like I known.
Now, exploring the VrayRT options, I've switched all the options to Expert... rendered...then I came back to Vray ADV and my rendering settings were set to default and changed completely.

This happens always you switch the render engine and you lost everytime your customed settings (both Vray ADV and VrayRT)

AFAIK this is the intended 3dsmax behavior and always has been. When switching the production render engine, the previous engine is discarded.
