Polyline/ interpolated curve doesn't work with points created in gh

Hi, I am trying to connect 4 points with a curve in gh - something i have normally no problem with… The two endpoints are coming from an intersection between 2 curves and the xy plane. The two points in between are adjustable. When I try to connect them, even with a polyline, it doesn’t work, but I am able to connect only 2 points each time with each other. The polyline connect only the two endpoint, and a second one the two points in the middle. Also an interpolated curve doesn’t work. When I Bake the 4 points in rhino, and input them as point in gh the interpolated curve works. I need to be able to continue drawing with those intersection points, because they are part of a bigger gh file, were this is a step in between.
Someone knows how it comes or what I could do? Thanks!

Make sure whether your input points are on the same data tree branch level or not…

@HS_Kim Thanks for the fast answer! What does tree branch level mean? I don’t recognize the icon you put inbetween, can you say the full name?
I just see the gh file you put with it.
