Grid generating problem

Hello,

we have been working on generating a simple gridshell structure divided in an ellips in karamba. But every time we apply the deformation, weird beams start to appear out of nowhere. Out of the starting point of the curve comes a beam which goes to every support point. Maybe it's clearer in the pictures but we have been struggeling to get them away. Anyone who knows what we can do about it?

Thanks!
