By "content" I presume that you mean content manager? Sessions are saved separately from the routes and have different KUID numbers so clicking on the route in content manager would not make the session appear. If you right mouse clicked on the session in content manager and selected View Dependencies then the route would appear as one of the required assets for that session.
In the case of "unknown" vs "known" author I can only suggest checking your user ID and KUID code in content manager - select the File menu, then Settings and click the Miscellaneous tab.
