Plex uses TheTVDB for TV Show information. As I have suggested on several other threads for Nova anyone can create an account on TheTVDB and update information on the site. TheTVDB is a community maintained site so if the information is inaccurate, which every instance of Nova I have seen referenced on on the Plex forum has been incorrect, it can be changed by a user that wants to take the time to update it. If no one wants to take the time to correct it then it will stay inaccurate for all users.
