Hi
This is a well-known glitch that occurs whenever you ghost inside a cylindrical part of uke (or if uke ghosts into a cylindrical part of you), it messes up the physics simulation for some reason when you continue the replay live. Unfortunately the only fix I'm aware of is to just edit before the 'teleporting' occurs and continue the replay from there. You can prevent the glitch in future by saving and reopening the replay any time you ghost into uke's legs or just by avoiding ghosting into uke's legs entirely
