(PKHeX) Error triangle on Legal Pokemon

[silentwarrior]

Hi! Some of my Pokemon have this red triangle implying they has a legality issue, but when I click on them it says Legal? Why this happens?

Hold control when right clicking the box slot and you can check legality without loading to the editing tabs.

PKHeX's editor has some automated fixes that likely corrected the error in the PKM's data.

I don't understand. It says something about Pokerus Days.

Is Pokerus illegal?

You'd have to look at the raw data to see what pokerus days remaining value you have, because the GUI is clamped to only legal values. Having wrong values from cheats / hacking in Pokerus / ROM hacks will do that.
