Volume Knob on Plate Amp Not Working

I needed to synch the firmware for my Plate Amp and Sub in order to link them. The Plate Amp did not automatically update. I finally got the unit Firmware updated . I had to reset a few times before I was able to connect via web interface, but it eventually worked. I tried the same thing (Reset) with my Sub amp to get the web interface to work and had to use the alternate wireless method to reconnect. I eventually got that to work too. Then I was finally able to synch the Plate Amp with the Sub but the process was very frustrating.

The Firmware release I used was http://192.168.86.105//httpapi.asp?command=SetUpdateServer:http://ota.rakoit.com/alpha but it seems the release build was loaded.

Now though, the Volume control on the back of my Plate Amp doesn’t work. Not sure it worked before the F/W update as I never tested it. It does work normally on the Sub. Both my units are now on the same Firmware release.

Is there a fix to actIvate the vol knob control? FWIW I have ACP Workbench. Here is the information:
