Playlists gone missing

Hi Folks been using LMS on Windows for ages together with a small family of Logitech Radios. I recently bought a Yamaha RX-A1060 Amp and although the Amp can 'see' the MP3s on my external drive and shows (and plays) them, the LMS display on the Amp DOESN'T show a heading for PLAYLISTS like the Radios although it DOES display 'artist', 'song', 'album' 'recent music', 'years' etc.

That surprised me! Does anyone know what I need to do so that LMS shows Playlists too?

Thanks

Steve
