Having hard time splitting kangaroo curves with surface


I am new to Kangaroo and I struggling to split Kangaroo based curves on surface. It comes out weird and renders weird. Attached are screen shots showing problem and the definition. I have circled the area where I am struggling to split the geometry. Thanks110821_Problems with Kangaroo Surface.gh|attachment (55.0 KB)
