When I use the right-click menu to send a file to the CD burner MC will send 2 copies of that file to the CD burner. If I attempt to delete one of the two copies both copies are removed from the list of files to be burnt to CD.
The only way to add an individual file is to drag it from an external window (Windows Explorer) into the CD burner window in MC.
