Rebar in shell thickness 2

[mdama]

Hello
I have a multilayer created with shell composite. The first and second sections are the same except section 1 has rebar layers. When I do "Render Shell Thickness" I see that for the rebar section, the thickness is much lower. I don't understand why? Is it due to the rebar layer? if so, what does that do?
Please see the pdf attached.

This might be just a visualization error. Make sure that all settings of the composite shell section are correct. Also try rendering shell thickness in the Visualization module.

Edit both "Section Assignments" and make sure the "Thickness Assignment" is set to "From section", not "From geometry".
