Notch problem for my wood assembly

Hello,

My GH is nearly finish... I have juste two problems:

    = The notch are not on each strata. and I don't understand because my GH file seems quite good.

    = At the end I want to bake the strata on rhino. When I do It just the first one bake

There is certainly a link between that errors but I don't find it.

(For Information: I want to bake the surface at the extreme right of my GH code.

GH file:     V21%5Bautosave%5D.gh

Rhino file: VR21.3dm

Thank you for your help
