I decided to do a zip code scan (I'm in Oklahoma) and see if I could find something new and when it was loading the full database, I noticed it included Indiana, Florida, and Missouri in addition to Oklahoma and Arkansas. I can understand Missouri being in there...sort of, but any idea why Florida and Indiana?
You have the full database enabled for scanning.
In the menu, select the option for "Select Lists to Monitor"
On that screen, you'll see an option to Set Nationwide Systems
Select that option.

There, you can turn systems that are used in many (if not all) states. Select a category.
With it highlighted, pressing the
E (enter) key toggles it between on & off.
Once you've done that, verify that your range setting is for your immediate area, not large enough to get into other states except those close by (Arkansas & Missouri, plus your home state).
