I have firmware version 2.7.2 updated on my 50s (H&K v10) headset and when I go into Sena Device Manager on my PC to make changes to the settings they are not saved to the headset.  On the Sena app I can't make changes to several of the options (i.e. Audio Overlay Volume Management).

I have Sena Device Manager version 4.4.18 on my Windows 11 pc.
