PirateRadio location of playlist

I installed pirate radio from th one liner provided in the tutorial. It worked find with the stations in the default playlist.
Following the recommodation in the README at github I created a new playlist at
This worked, but the stations pop up twice when itering throu the list with the buttons. In the web interface they are also shown twice.
The file /etc/vlcd/default.m3u contains the same stations without any action of my side.
How can I achieve that the stations are listed correctly?
