Radio Paradise 16/44.1Hz Stream

Hi all. After listening to Radio Paradise for the past year via Volumio I am no longer offered the alternative mix option at at 16/44.1Hz bitrate. Is this a) a licencing issue with Volumio b) a Radio Paradise change or am I missing something in the settings? Help would be appreciated as streaming lossy formats is killing me softly.

Do you use the RadioParadise plugin?

I do, and I realised that it had somehow been switched off. Switched it back on and all good now. All options in RP showing up.
Thanks for the response.
