Ominitype On Giratina Not Working

Even though on the Omnitype webpage it said that the user should take neutral damage from Fairy, Ice, and Fire, when Giratina got hit all the attacks were super-effective. I’m assuming this is a bug? And I know it’s not Omnitype just outright not working, because if that were so then Giratina would resist Fire.

Yeah, omnitype isn’t working as intended. However, Giratina would be hit neutrally with fire, as fire hits 4 types SE and 4 types not very effectively.

I know, I was just saying based off his normal typing it’d be resisted, but thanks, i was just wondering
