Spotify playlists not refreshing without mopidy service restart

using mpc clear and mpc add “spotify playlist uri”, the playlists never change from when they are initially loaded.

The only way I can refresh the playlist correctly is by restarting the mopidy service first:

sudo service mopidy restart

note: removing the cache files makes no difference

sudo rm -rf /var/cache/mopidy/*
sudo rm -rf /var/lib/mopidy/*
