The Revision Number Component List as I created it, was: A, B, C,... AE. At the time, those seemed sufficient. Now more Revs are needed.
After editing the Revision Number Component list, the list now includes new Values in the List, AF, AG, AH,...BZ.
Saved and restarted admin, the new list is visible.
But when attempting to Set Revision, my list of choices still ends at AE. What else needs to be done to make the added Revs available for Set Rev?
