If you want to hide the playlist title a new line has to be added in the CSS editor:
.playlist-row .title { display:none; }
The reason of why it’s not sufficient to just write “.playlist-title { display: none; }” is that the class “.title” is placed as a subclass to the playlist-row, as shown in the reference (html source) inside the li tag ( <li> </li>).
