This is not the easiest option, and definitely not the only way.
Another option is to use “Reassign to another” stage from the scores Review screen for each shooter on the duplicated stages, but that is not the most efficient way.
@Rich_Simmons if you have Android device with PractiScore app installed, sync all tablets to it, then open the “Build Stages” screen, then tap and hold on these duplicated stages, then you will see the “Merge” option at the top. More on that at How to merge duplicated stages
