Bad Neighbor won't unlock

[Partik24]

I've turned at least 6 neighbors into ghosts with the ghostify power and caught them with a ghost zapper/my cat and the challenge will not unlock. It's not just the trophy that won't unlock, it is the in-game challenge as well. I've tried going over to their house and doing it and I've invited them over to my house and done it. I've also loaded previous saves and I've deleted my game data. Anyone know why it might not be working?

 

EDIT: Okay I figured out why it isn't working, you have to go to the house that's within the same map as your house.
