The Scale 3 Mac app did not show up the Chord progression, created in the Create page in de C-section Main Track, in the arrange page. I have tried many suggestions from the web and AI but no track is shown.  
When I use the same chord progression when I use Scaler 3 as a plugin in Logic Pro all performs well.
