Web API: audiobooks getting returned alongside shows?

[DaveCa]

Hullo - If I add an audiobook to my library I see reference to it returned by both the 'get my saved audiobooks' endpoint ( GET /me/audiobooks ) AND by the 'get my saved shows' endpoint ( GET /me/shows ).

Is this expected / known? So that I don't show this audiobook under saved shows: do I need to fetch saved audiobooks first & then subtract any shows with an id returned by the audiobooks call? I don't really see any aspect of the results from the 'saved shows' call that would indicate this entry is in fact an audiobook ...

Sample book that demonstrates this behavior: "Last Rites" by Ozzy Osbourne (id=4AJ5xz1wsrzgZHSEhqzTmI).
