Unable to delete points

Unable to cull (remove) the points in green (from image) from naked points of mesh, split tree not working, [want to delete the {0} branch so as to not apply load at the base of cylinder mesh intersecting the planar meshes for kangaroo mesh relaxation.

Look at the Negative output of the Split Tree component… it should be your tree without branch {0}

tried, not working

Can you post a Grasshopper file with the Mesh internalised in the NakedVertices component?
