Symmetrical Lighting Issue?

I have two walls that are symmetrical to each other that I want to light up exactly the same.

The problem is that when I try this there are some differences in the lighting/shadows? Even though my wall designs are symmetrical and so are the parts emitting light to them, the lights and shadows are not.

I have tried to redo my entire wall, re-position my lights, and change the light technology but none of this has helped.

Here’s a screenshot for reference.

To me, the lighting looks symmetrical so could you explain? I can suggest making sure that there isn’t any other light like sun light influencing your lighting but that is all.
