S970 chord fingering, what the heck??

Okay, now that I am getting down to playing, and not just playing around, went to the chord fingering setup, and after testing EVERY single one, I cannot play a clean E flat M chord in the acmp! the only time it comes out clean is using full keyboard mode. Done pulling my hair out, what am I missing?
I am a trained pianist, but have no problem chording with my left, as I did on the 910. But, every chord I play, other than C Major, shows the chord as F/C, or G/C, etc.
And, when using full keyboard mode, I have to constantly keep turning left hand voice on each time i switch to style B, C, etc.
Thanks in advance!

Well, as usual, after some patience and time, I went thru most of the settings again from the ground up . . . fixed the issue. . . but please dont ask me which setting it was that caused it . . .lol

All fingering options are working just as my 910 did.

Do yourself a favor- do a full factory reset before you start creating and saving registrations, etc.

Usually the unwanted " /C" bass is caused by the MIDI settings. The keyboard may have been connected to a pedalboard, and it's expecting a bass note from the pedals.

Thanks Ted, I did end up doing a reset as well . . . have not set up my reg buttons yet, figured it was a good idea.
I appreciate the input!
