Has been happening for a long time now. Used to work, at some point doing LZMS fixed building, then using -e broke completely. Omitting edition then builds a 20-in-one using the specified language. All builds have a boot.wim that mislabels the indexes and requires manual intervention, and mislabeled core/pro indexes in install.XXX.
Former UUPMC build created Enterprise G, with the errors above, but it worked. Current does not appear to.
