You should post a permalink to the problem area. Use the "link" icon in the lower right corner of the editor and copy and paste the URL that appears in the browser when the page reloads.

And provide more details about the problem that has not been corrected. It may be that the editor submitted a correction to a third-party database that has yet to implement the change. Errors in navigation to points-of-interest sometimes happen because Waze uses location markers from Google Maps, Yelp, YP.com or Foursquare.
