Hi Mary,
These are definitely duplicate titles, the manually added ones are below the duplicates. Even if I use the default section name, or change the format, it does not seem to clear this redundancy.
Right now the course format is "Topics", which is the setting we want to use. The same thing is happening using the weekly format though.
All of the courses were copied over to the new 3.1.9 server by the server administration team at the end of November. This was not happening on the old server so it seems logical that something happened when the courses were cloned to the new server. Is this something that can happen when courses are upgraded to a newer server?
