Scanning through performance styles fails to recognize chord pattern

Logic 10.6.0 / OSX 10.15.7

As I scroll through performance styles and articulations Scaler at some point, fails to recognize the saved chord pattern and starts to report back only the singe root notes from the midi track in Logic. Midi drag still works OK though.

No other plugins or midi effects. Using Kontakt 6 FWIW.

Cheers.
