Retail customers won’t leave lot

Hi! I am currently doing a rags to riches gameplay and I am having some issues. He opens the store and sells just fine, but I’ve had people randomly stealing my products and when I close the store, everyone just mills about. I have played with a store a while ago and I thought that everybody left as soon as the store was closed. The most annoying issue though is that people are walking into the store even when closed. His home is on top of the building so if he’s sleeping and people are walking in, I can’t fully fast forward. And it’s not just a couple people, it’s large groups that don’t have the Socializer, Loiterer, or Customer thing above their head. They’re just there and they come in to listen to music. Fame is turned off so they’re not fans. They’re just hanging out inside and outside for hours. I have some mods that are all updated, this is a new save file, and I just really need help because I don’t want to have to lock the front door of the store every single time I close the store. Thanks!
