Can't edit chord inversions

Having placed chords in pattern one I then go into the edit page in order to alter the inversion of some of the chords. When I click on octave or the inversion + or - I can hear the change in the said chord, however when I play the said chord from the original pattern it hasn’t changed the chord it’s in its original form.
Playback timings and performances work perfectly any changes are heard on playback of the pattern.
I’m wondering if I’m doing something wrong or if it’s a bug . I never had any problems with Scaler 1 with this issue.

Found the reason Global voice grouping was activated. Now working fine.
