maybe w eneed to explain what the reference frame does? as the name suggest its the frame all translations, rotations, scales are set to 0 hence no movement. every other frame has a value relative to this frame.
say frame 1 the track is on x0,y0 and on frame 10 the tracker is at x50 and y200. if you draw your shape on frame 5 the tracker will have values other than x0 y0 and thereby moving your shape a bit once you apply its data. if you shift your reference frame in the tracker to frame 5 the shapes stays where it is and everything works.
