Problem with splines

So I’m working on a system involving splines, Each of the green points is a “path” point, the blue is a “wall” point, and the yellow is a “door” point. Ideally, each green path point is connected to 2 other path points on the next layer. (which its doing correctly) however there is an additional spline point seemingly at the origin that is connected to every path point. As seen in the blueprint I’m clearing the points before I set the others so I’m not entirely certain how every point is going back to the origin
Any advice is appreciated!
