How come the output volume is lower after updating the UC mixer software and the 192 Mobile firmware?

I use my Studio 192 Mobile with Cubase so I have the UC Mixer set to "Mixer Bypass". But, like all geeks, I noticed an update for the UC Mixer software and updated to v2.4.0.44938 and then a subsequent firmware update for the Studio 192 Mobile to DSP v1.7-7. Now the output volume is much lower. I am not sure which update cased this as they were updated concurrently before I tried the updated UC software.

Prior to the updates the Studio 192 Mobile "Main" volume was always set to near 12 o'clock. Now I must set it to 3 o'clock to get a similar volume. Same for the headphone volume knob, prior to the updates it was set to about 1 o'clock, now I must set it to 3 o'clock to get the same volume.

Any thoughts or suggestions? Thanks

Oh well... I never learn to leave things be when they are working good. I mean, it is still working good but, now it seems I lost a bunch of headroom control.
