Asteroid contract condition won't trigger ("Have your vessel near Gilly")

• A detailed explanation of what happened and what you were trying to accomplish
  Trying to complete "Bring a newly discovered Class D asteroid into an orbit around Gilly."
  "Have a newly discovered Class D asteroid in tow" and "Maintain stability for ten seconds" are checked, but "Have your vessel near Gilly" doesn't seem to want to clear. I've tried orbits at different altitudes and even landing on Gilly. Also tried in both 32 bit and 64 bit versions of KSP.
  I tried searching for this issue but I didn't see it, so I don't know if I'm just doing something wrong. I imagine if it were a bug, someone else would have mentioned it?
