Problem with syncing audionooks

Hi

I have an iPod shuffle 4th generation ..

I have a problem with syncing audiobooks. I have the audiobook file at my desk. When I drag and drop to the audiobooks section in iTunes it doesn't go to it's right place. Instead, it goes to the music section.

I tried to restore it but the problem still there..

can anyone help me please ?

Thank you 🙂
