SUMMARY
CD tracks that are medleys typically separate the names of the songs in the medley with slashes. Whatever code handles escaping characters in the file names for tracks doesn't notice this, so that the medley will appear in a directory named "<track number> - <first song>", with a directory hierarchy for the second to next to last songs, at the bottom of which is a file containing the whole medley named "<last song>.<extension>"

STEPS TO REPRODUCE
1.  Find a CD with a track that features a medley, such as "Common Ground: Voices of Modern Irish Music" (on MusicBrainz at https://musicbrainz.org/release/1ff35d87-32ca-41f3-b336-e6c27b2a0fbd)
2. Rip it.

OBSERVED RESULT
The directory holding the files from the CD will include a directory named "10 - Whistling Low ", within which will be a file named " Errigal.<extension>" that holds the medley "Whistling Low / Errigal", which is track 10 of the album.

EXPECTED RESULT
Among the files from the CD should be one named "10 - Whistling Low / Errigal.<extension>" holding the medley "Whistling Low / Errigal", track 10 from the album.
