Ipod Classic "one the go"-list sync to back

I am useing the ipod classic 128 gb with windows and the latest itunes version.

I realized that since the new itunes version (I think it was since 12? ), the "on the go" list which I made on my ipod,

isn't synced anymore back to itunes. I selcet tracks, add them "on the go" and save the list after.

However the list is not syncedback to my itunes. First I thought it's a bug in itunes but it's still not working.

I can see my ipod I can transfer music.

Does anybody have an idea?
