Delta Milotic Error?

I was just wondering why the Pokémon Insurgence Wiki says that Delta Milotic is immune to ground types. It’s a ghost type Pokémon so that really doesn’t make any sense. Is it actually immune to ground types or is it just an error in the wiki?émon)

The same thing also applies to Delta Feebas so I don’t think it was done accidentally

It is accidental. My guess is that the type grid was copied from Misdreavus or Mismagius to save time and whoever did it forgot to remove the Ground immunity.

Oh ok thank you that makes sense
