Can't get Shiny Meltan legal in Shield

[Hydration6555]

Hello everyone! This is probably a very stupid question, but I am trying to import the shiny Meltan from Pokemon Home that is in the events gallery into my Shield save with PKHeX. However I keep getting an error saying that the Home tracker is invalid. How do I properly import it into my game?
