Remove bad url alias from g.d.o/drupal-marketing

Through editing and then publishing a custom home page for g.d.o/drupal-marketing (./node/99), a pathauto alias has also been entered making the default path g.d.o/home -- while ./drupal-marketing still works, all system-gen email and og_panels itself thinks that the canonical path is ./home.

Can somebody please delete the errant pathauto entry for ./home? I really have no idea how it happened, which is the disturbing part.
