Hi all,
seems to be a small issue with Cubase 12.0.30 Build 286 on Windows (10).
having an accord track with some chords and ‘show scales’ = on.
Selecting the chords including scales-name and try to drag&drop to an instrument track won’t work, whereas selecting the chord-symbols without the scales-name will work. As said, just a very small one 
Regards
Karlo
