Help me figure out why location preferences on facebook ads aren't working

---

I'm running a facebook ads campaign for a local event and I put in super narrow location targeting (the city the event is in + 30 miles) and yet on one of my ads over 80% of the geographic traffic is from other states. In another campaign - 67% of the geographic traffic is from other states. I have several ads running (as I'm in the testing phase), but the majority of traffic from every single ad is from other states. I need to get this figured out as I'm clearly burning money when most of the traffic is going to people who won't even be able to attend. I shouldn't have advantage+ location selected as I'm using original audience and running a custom audience.
