Delete seam lines on a lofted surface

Can anyone please help me to remove the seam line shown in the image? I am also attaching the GH file. It seems to be generated in the lofting process, I only want the surface to be displayed without this line.

Basically it is a closed surface generated after lofting a series of oncentric 3-point arches. I need to export the surface to .iges but the arch line is visible and does not fit the purpose.

Your assistance will be much appreciated!

Create the same object manually in Rhino and compare it to your baked version from Grasshopper. It looks like a normal NURBS seam that you can usually just ignore and won't bother an IGES export. Compare it also to what you see if you create a simple NURBS sphere in both Rhino and baked from Grasshopper. Such seams are for everyday purposes just a mathematical formality of how Rhino creates single surfaces into domes, spheres or a torus as a single untrimmed point editable surface. If you really want no seam, you'd have to drape a rectangle over it and trim the edges.
