AFAICT, the ones that are missing in Symfonium are empty genres. Not sure why there is a genre if there aren't any songs to go in them, though. Which means this IS a Jellyfin problem. Here is a screenshot of mine. "Abstract" is present in the web browser, but is clearly empty. I'm guessing Symfonium just drops the genre.
