How did you merge the libraries? From the Calibre, using the Copy to library function? Or moving the files directly? The latter is NOT the way to do it. Calibre does not *see* anything you do with the files and those changes won't get recorded in its database. All actions must be done in the Calibre program, not with the files themselves. Now you just have to re-import these invisible books, using the Add books button.
