Physics Constraint Bug On Reload Level

I created a BP that contains a steel rack that rotates around the Y axis using a Physics Constraint. I then attach 8 white steel targets to the rack using physics constraints, so when the rack rotates, the targets rotate with it. The player can then shoot the targets, which breaks the target’s physics constraint and the targets fall off the rack. This works fine but I’ve had an issue with one or more targets/physics constraints freaking out when I reload the level. I use level streaming to load levels, so to reload a level I unload the level and when it’s completed unloading, I load it again. The targets only freak out when I reload the level.
