By the way - the State display name can be anything but the KEY NAME should be ALL CAPS and NOSPACES (not strictly followed by PTC. Some trouble if you ever use Java code to refer to the state (like branch on a state or prevent something).
Can tell if the rebuild is successful by starting a new lifecycle template and seeing if the new state is available to select.
I think it's still true that states are not listed alphabetically so look near the bottom of the list.
