Is my shader acting normal ?

Hey guys i’m working on the shader of my game, where you are holding a flashlight, the shader is working good except with the ■■■■■■■ flashlight (too bad half of the gameplay is based on it ^^).
As you can see on the images, the rounds of the light touch the walls but there is still some shadow on the bottom of them. I don’t find any solutions on that, is it normal ? Is my shadow clut wrong ? or is it the parameters of my directionnal light ? I’ve tried to tweak a bit everything but nothing works

Oh yeah, you can’t see anything on a phone. Here there is more pictures with improved luminosity, as you can see the circle of my lights act strange on the wall compare to the floor.

And here a link to a video if it can help :
