True on the scan part, but that also doesn’t explain why would they provide the map of the living world showning both the Outer Space that contains Earth and Demon Realm in the same space as it is clearly shown here.

“Outer space is the upper portion of the living world, and is the realm where Goku and the other main characters live. It is the only portion of the
Dragon Ball world that even remotely resembles reality, being based off of the actual universe. As such it consists of planets, stars, and other celestial bodies.
Daizenshuu 7 explains that in the
Dragon Ball universe a collection of planets forms a nebula, and a collection of nebulas forms a galaxy; in actual modern astronomy, nebula are collections of space dust and gas rather than planets, though the term was originally much broader and did include galaxies. Galaxies within Universe 7 are divided up into north, south, east, and west. Universe 10 seems to follow this same scheme, as the
Dragon Ball Super manga states that Zamasu was previously Universe 10’s North Kaiō, but it is unknown how or if the other universes are divided”
