Is this a bug? (video)

in Scaler 3.1.2

Please note the G/B chord. When I click on Voice grouping, it changes to G.

Not a bug, Voice Grouping changes the voicing to voice lead and has to revert to the pure form of the chord which is a G Maj. So as expected there.

OK.

So is it possible to have G/B, after Voice Grouping, still remain G/B instead of turning into G?Because Voicing open can drive the Kontact NI guitar content very well.Can we think of a way to make G/B, after Voice Grouping, still remain G/B?
