How can I get the FindMy app to display my correct home address

I have deleted my AirTags multiple times and tried to address the problem of the FindMy app is showing my house number, road and zip code correctly, but the town is one about 15 miles away. It often doesn’t recognize that my devices and items are home, causing alerts that I left them behind when I go to the barn. Is there a way to get my house back to the correct town? It doesn’t seem possible that it can get every thing correct but the town, the only phone the AirTags can ping off is my phone or devices since neighbors are quite a distance away. This town only became a problem when I added the AirTags
