Previous Playlist

Version 3.233
Bubble upnp is the control point
Volumio is the renderer (raspi)
And Asset Upnp is my server.

I add songs to my playlist in Bubble. It will play the list no problem. If I clear the playlist, add more songs and start playing the songs, it starts playing the list but when the first song is done it plays the last song from the previous list. It seems to do this constantly. Anyone know how to fix?
