Some radio stations no longer work

Hi, as per title: not sure exactly when it started. 2 stations that I had saved as favorites no longer play (the other 3 play fine). I then tried to access them (actually, just the one that's local) via radios>local radio, same result. Basically, I can see what track is playing on the station, everything looks normal, but instead of the pause button option (while music plays), I see the play button, & pressing it does nothing.

Thanks. I'm on a duet via ipeng, using 7.9.2/r1552283404
