How to create diagrid symmetrically on a lofted surface

Hi guys,

I am trying to make diagrid panels on a polysurface that I have morphed within Rhino. But when i make the diagrid panels the areas near the funnels get weird. If you look at the image below you can see the diagrid at the funnels are not symmetrical. Is there a way to fix this? i have attached the rhino and GH file (even though the geometry is internalized). I am gonna create a steel frame structure from the diagrid hence I want it to be symmetrical. Basically I want the design on the funnel areas to stay the same. Thanks!
