Vray Next - Light select problem

[CG_FORM]

Recently I noticed some weird errors of Light Select element. Here are 2 examples: First - the production render doesn't show the Light (sunlight) used in the scene not only in Beauty pass but also in all other (like Light select pass). What is weird the same sunlight is visible when rendering in IPR mode.
Second issue is very weird looking Light select render element. Since one plane renders quite nice the second one is full of artifacts. Do You have any ideas why?

The two issues are maybe related, but I'm not sure exactly what happens. If you can get me a scene to vlado@chaosgroup.com I will be able to tell you more.

Best regards,
