This can happen when an area is not mapped entirely or when an address is not entered correctly. In cases where you can be more specific, you can use the exact address and not abbreviate: “road and not Rd. street and not St., boulevard and not Blvd, etc.”
In cases of Canada, the USA, the UK, Australia, and most European counties, try and write the address with zip codes or postcodes included. This will greatly increase accuracy.
