Updating destination urls to final urls in adwords could have been smoother. Here is the process if you are still having problems. If you don’t need advanced tagging do it through the web interface-not the editor. See instructions below.
One other comment. In Adwords editor the destination url and final url should switch places to make life easier. This is more of a request for Google. Good luck:
