When submitting a new game or variant entry, the help text for the "Description" field says something along the lines of "this could be the description from the back of the book" - surely, this was meant to read "this could be the description from the back of the box"?
When adding a new boardgame the description field note says:
"Please summarize the theme, game-play, and goal of the game in 1-4 paragraphs. Off-site links should be reserved for the links section."
When adding a version it says:
"Please attribute the source of the description. (E.g. From the back of the book:, Publisher Blurb:, User Summary:, From Wikipedia:, etc...) If you attribute Wikipedia, then please include a link back to the Wikipedia page."
If I recall correctly, versions were first introduced on RPGG, where the book comment made sense, and then later on adopted by BGG. So the text needs updating (to "box/book").
