Sword/Shield - Invalid PID+ Correlation

[GodMachine]

I'm trying to edit my new Pokémon Shield team, but I keep getting this error.  It only happens for the Pokémon I caught in the wild (mostly overworld, but some hidden; that "!" from tall grass).  It had no objections when I edited my starter.  I did this recently (about two weeks ago, just after the latest PKHeX update) with my Pokémon Sword save, and I didn't get this alert, so I'm not sure why it's doing this now.

Use the encounter database. 

Different types of Pokemon have different patterns that they are generated with, and some have detectable relationships between values that are expected to be present.

Is there a guide/tutorial for it?  Apologies for asking, I'm just not finding one.

I'm also confused why it's doing this now, but two weeks ago, I wasn't getting any errors when I modified my team in my Pokémon Sword save?  I just changed their IVs and went right back to playing.

Different encounters, different restrictions. 

The encounter database is pretty straightforward, just experiment with it.
