I have set the target costumer to ban ghosts and occults from appearing on the business but they appear anyway. It happens every time I open the business.

Commenting to say I also have this issue where I have set literally every other occult to be able to visit except for ghosts yet I have minimum 3 show up per "shift opening" (as in I just run the day for at least 8 hours). I have followed most of what OP has done except the "no ghosts" sign.
