Error with Ladybug Solar Analysis Mesh

Hi all!

I have been trying to run a solar analysis using Ladybug together with Skin Designer. This is the script I have been following: Responsive_Environmental_Facade_with_Ladybug__and_SkinDesigner (
I have been following the exact script posted above. However, the final output, i.e. the mesh, comes up with these verticals which interrupt the mesh. Not sure whether anyone came across this before. I have attached a picture for refrence.
Any ideas about why this happens would be much appreciated!
Many thanks,

I would recommend increasing the offset distance from the base surface.
