Today I was also importing some .pgt and .pcd files, and my main issue regarding Worlds 2008 Lucario, is that after receiving the gift in-game from the delivery man, Lucario seems to be fine but after loading the game in PkHex, that's when things starts to be weird. My Lucario is a red Blank space in my pokemon's party Slot. I can't view its information or edit either.
PKHeX (190515) version
First I've tried with the regular .pcd and .pgt provided and downloaded from these 2 links, imported and then saved changes.

Then I also used the .WC4 downloaded from here

After saving changes in PkHex
Using this .pcd really works to see the little description, but the end result it's always the same, I can't load Lucario's information in PkHex, always a red blank space.
The only thing that kinda seemed to work was to import Roc's PC .pkm files direclty into my save file.

example:
Just in case I have also provided my .sav file.
