Issues with lighting and sprites

Hello guys!

I’m creating a prototype for a 2D game and I’m having some problems with lighting and sprites.

What I want to do is use one specific light source to light one specific sprite, and I want to do the same with another light source and sprite. I tried to set them on different light channels, and all lights and sprites are movable, being able to cast dynamic shadows. I can’t figure out what I’m doing wrong here.

In the image, the lower light source is lighting the upper floor and his assets. I tried to use lighting channels, but with no success.

Can you help me with one solution or tell I’m doing wrong here?

Thanks!
