Backup Voice Memos

Hi,

I have 217 Voice Memos and would like to copy them into my iTunes Library. When I synch the phone to iTunes and click on Devices-Voice Memos the full list appears. When I click my Voice Memos folder in the iTunes library I only see 123. I have already clicked on my iPhone in the Devices tab and pressed Music-Sync Music - Selected Playlists and also checked 'Include voice memos' but they just wont import. Please tell me what I am doing wrong.

Thanks
