Reflections going through object.

I have a scene with reflection captures and ssr enabled. @NasteX - Yes, I unchecked this option.

So let’s begin again… I have a box reflection capture that covers the entire scene. Next I enabled SSR and set the intensity to 100, the quality to 100 and max roughness to 1.
My goal is to get a soft blurry wooden floor like this: WithoutPlanarReflection.pdf (535 KB) The problem: I get some wrong reflections at the edge of the screen like under the sofa → it should be dark.

After placing a planar reflection capture in my scene on my floor i get something like this: WithPlanarReflection.pdf (574 KB) The problem: I get strange white lines around the wall, the floor is too shiny and not soft like on the image WithoutPlanarReflection.pdf (535 KB)
Fixes: it fixes the edge problem and under the sofa is dark what i expected.

What happens in the original scene if you put just a simple editor box mesh to where the wall is?

I put a editor box mesh to where the walls are and this makes no difference because I already have double sided walls.
