Hey guys, Just a quick one here. I'm on the most recent version, searching for a Vivillon to spawn, and it's returning no results? I've reset all the filters etc, but you can definitely find Vivillon in the wild, so I dunno whats happening here. Can someone explain please?

I'm trying to spawn in a Cryogonal with the Blizzard Mark, which according to https://www.serebii.net/scarletviolet/marks.shtml, is found on Pokemon 1/50 times when they are caught in a snowstorm. I've applied it in all 3 areas, and it's caught in the Glasedao Mountains, where there are snowstorms, but I can't find out to make it legal or where to check that it was caught in a snowstorm for PKHex to recognise it. Can someone please help me with this? 615 ★ - Cryogonal - 248651248553.pk9
