Perhaps it was intended on the site or it was a mistake and it should have included the duration (outside of Revisions), but obviously in-game this will show in the tooltips anyway so there is nothing to worry about.

As for for the other stuff, honestly the descriptions (despite a few little bits of potency discrepancies on certain jobs) mostly make sense, maybe people who don't have English as a first language may find some confusion with them. Although a number of these actions have had the same description for years so can't see them suddenly being changed.
