If you duplicate any CPs with that ABS prefab, make sure they all have new names, link to each other properly and that the new cp entity (not the prop) has a unique index.
If you just remove 3 CPs from the 3 stage ABS prefab, remove the stage entities and you should be good.
If you use the gravelpit-style a/d prefab, just set the only previous required CP for all the CP entities to itself and they should be good.
