Voice memo's on iphone are not placed in itunes voice memo playlist

Hi

I use the dictaphone app to record classes (so my memo's are way too long to send).
Untill now they were shown in a special playlist, but not today.

They are on my phone but not in the different playlists (voice memo, recently added)

Has anyone got a clue what I shoud do to get those memo's in my itunes?
(The box include voice memo's under music is on).

Thanks!
