Why is extruding a bezier curve making these loops? After extruding one time or subdividing the curve, if I try to extrude again, I get a figure 8 loop. I've used bezier curves before, but this is the first time in 2.9. Anyone know how to work around this?
This type of extrusion actually splits this control point and adds a new one in the middle.

It's not obvious that it happens since they are in the same location.
