The process can be laborious if there are a lot of errors, but it is doable.
1. Go to Reports...demographics...city= ... and put in the incorrectly spelled city.
2. Run the report
3. Correct each of the patients demographics by clicking on their name in the report and going to their demos page
4. Restart AC and the incorrect spelling should be deleted from the drop down list IF you have deleted every instance of the error.
