If I split the curve and try to move the split point, after finish editing the point is not moved.
This bug seems to be related to the Sketch020 having constraints being referenced from section_d_sketch.
If those constraints references are removed then the issue doesn't happen.
I also noted that if I try to edit the split over and over it may cause FreeCAD to crash.
In this file curves_bug.FCStd.zip we have two sketches and a joinedcurve.
