Exported sav files aren't the modified ones?

I'm able to export my save file into PKHeX, modify my Pokemon as I see fit, and export the save file afterwards. When I import the modified save file back into my game, it seemingly doesn't read the modified save file and just uses the old, unmodified save file. It's not game-breaking or anything, I can still play my game, but it's just annoying that I can't get PKHeX to work.

Right click and set the modified Pokemon back to the slot.

Worked like a charm, thank you very much!
