Map typo remains after 25 years

I just picked up 1:50,000 topographical maps of the Canadian part of the Chilkoot Trail, and found a major typo on a map that was printed in 1984 and corrected in 1999 (104M/14). Not only is the park not “Childkoot”, Parks Canada says that it shouldn’t even be “Park” in French, but “Lieu historique national du Canada de la Piste-Chilkoot” – and Parks Canada has plenty of hyphenated-Canadians so I’m sure is right.
