The “City” field of your address in your public profile should only contain the city of your main office address. If you’d like to add the different cities/areas you serve, you may add them to the “Service Areas” tab of your profile.
Make sure you add each area individually in the "Add a new service area" section, don't just copy and paste the list as one entry. For more information, see How do I add/remove a service area to my profile?
