ghost geometry in wireframe 3dsmax 2016

[priad]

Hi everybody,
I have a strange thing since some month: as you can see on the sprint screen, I have ghost geometry in wireframe which disappear when I turn on smooth...?
The white geometry can't be selected, this isn't a proxy, Xref or something like that.

Someone had the same problem? I'm on vray 3.3 and 3dsmax 2016.
I really need to solve this, thanks for your inputs!!!!!
