Trying to use occlusion culling in a multiscene setup (Hdrp 2019.3.3)

So I have 3 scenes, wich I run at the same time in the editor.
2 of them has Geometry and the 3rd is only systems for the character.

I'm trying to bake the occlusion culling with the 3 scenes at the same time but when I play, the result is all wrong and I get tons of rendering at some place.

Next I tried to bake each scene individually, same result.

Then I move all the Geometry in the active scene, bake, and then move it back, same result.

Finaly same thing, but only bake on active scene (disabling all others) still not working.

Help please.

 

Turned out I deleted the Occlusion folder in Library, then baked again and it's fixed.
Some dynamic light using shadow are not renderered however (the light appear disabled) ,it fix if I turned off shadow, is it normal?
