If you are an admin for your account, you have the ability to cancel and remove a location from the location manager.
Select MyAccount > Manage Locations and Competitors > Search for the Location > Uncheck the box to the left of the location that you wish to delete.
The platform will show a pop-up window asking you to confirm that you want to delete the location.
You may need to refresh the page for the location drop-down box to properly refresh. Otherwise, you should be all set.
*If you deleted a location in error or, perhaps a location has reactivated for you, you have options: Click the "Show Deactivated Locations" button to show the previously removed locations and re-check the box for the location you wish to reactivate. The dashboard will take up to 24 hours to re-populate that location's data.
