Blend shapes normals are wrong.

I have created a simple petal blend shape in blender.
It consists of two blend shapes, half open and fully open.

I'm using HDRP.

On a picture below you can see the single petal on the right in it's open state and the 4 petals on the left in base state.

Unfortunately when the blend shapes are applied the petal normals don't look right.
Petal on the right should be completely greyed since it's faces are in opposite direction to the light.

On the picture you can see the import settings I'm using for this model.
