When transferring mons from Pokémon ruby rom to Shield via PKHex, it says it was hatched in Galar

Basically the title. I'm trying to shiny hunt in the OG gen 3 games and I don't have physical copies, so I figured transferring them through PKHex would work. But when they arrive in Shield it says they were hatched in Galar. I want it to show that they were from Hoenn. Any reason for this/a fix?

I'm guessing you genned them incorrectly.

PKHeX can simulate transfers properly.

Upload the PK3 here, I'll show an example.
