Why are most of my Galar mons marked as illegal?

[Irina]

They are all listed as, "Invalid: Encounter Type PID mismatch"

How do I fix this? Or can someone fix it for me?

I'm assuming it's because you edited them? Read the changelog for the updated PKHeX.

There presently isn't a public way to bruteforce the PID IV relationship on Overworld/fishing encounters.
If anything, if they don't have the brilliant aura, you can't even make them have Flawless IVs.

Just remove any marks, set them to hatched.
