Geodude's entries for what it learns at lvl 12 are different depending where one looks

Question

When one searches up magnitude, it says that Geodude learns it at lvl 12. However, when one looks at the Geodude page, it says it learns harden at lvl 12. Could something be done about this?

Answer 1

"These Pokémon learn Magnitude at the level specified. The numbers given are for Pokémon Ultra Sun & Ultra Moon and may vary in other games; check the respective Pokédex pages for details."

Geodude learns Harden at Level 12 in BDSP.

This is not an error.
