I don't have a way to trade Pokémon to evolve pumpkaboo, phantump, or swirlix, so I tried to just change the species in pkhex to their evolutions. When doing this, it says that it cannot match encounter from origin game. This is the only thing about these Pokémon I have changed and I can't figure out what the problem is. Can someone help me figure out what's wrong?
