Shadows of static Objects not affecting Dynamic Objects correctly after using LPPV

I am using Mixed mode on Directional Lights and my Realtime GI and Mixed GI - Subtractive are selected in the Lighting window. All static objects are baked properly. But shadows of these static objects are not affecting the dynamic objects properly even after using LPPV.

I tried creating a plane on which a cube is positioned as a thin pole which are static. Now, if I roll a sphere (dynamic and has LPPV) near the shadow of the pole, it doesn't appear normally. The whole sphere is covered with shadow, instead of the small thin shadow of the pole.
