Shadow on the light

[newfriend]

Hi, I have a huge logo on the wall. At the day time we can see the normal grey shadow behind it. But then I'm trying to make a night render and here we are. Back side of logo is highlighted an er can see the back light. But, also, we can see the grey shadow over the light in square and below G, M letters are have a shadow over the light. Is it normal situation? The plug-in version is 3.3.2.68.
