Volume Display On SB3 in db

Sorry if this has been asked and answered somewhere else, if it has I couldn't find it.

At some point between LMS versions 7.9.x and 8.0.x the volume display on the screen on my 3 SB3's changed from a horizontal bar to a written db reading IE "-35 db"

I think that it was the change from 7.9 to 8.0 that this coincided with, however I'm now on 8.0.1 and I've just noticed that the display has gone back to the horizontal bar.

Is this a setting somewhere ? I rather preferred the "Gain" reading rather than the bar.

Thanks

Jeff
