I'm having lighting problems

I've asked on forum, but i didn't got any clear result. I got that scene setup:

• 1 x Directional light which i set both Realtime and Mixed

• 2 x Baked point light over two sides of the plane

• 2 Meshes, the left one is marked as Statis, while the right one is not.

• 1 x Box standard unity mesh (Size 20 x 1 x 10)

Tryed unity 5.2 and 5.3.1p4 and the actual 5.3.2

I was trying to bake a scene using using a Directional light as sun, but i'm having some trouble there, using the Directional light as Realtime/Dynamic don't allow me to lit the scene from underneath, as you can see, the right viewport, light isn't affecting even the baked lightmap is generated correctly: As soon i set the Directional Light (the sun) as Baked, that happens Underneath lights render correctly, but i can see dynamic sgadiw from the right mesh rendering trough the main box.

Actually global illumination is causing me more trouble than helping since Unity 5.0 :S

Is there a way to fix this?
