P2020 Custom palettes Broken?

Hi all,

Anyone else experiencing any issues with Painter 2020 and Custom pallettes?  

Seems to me since Ive updated to Catalina on my Mac (The issue may have been present in Mojave as well.) I am unable to customize any custom palettes.  I am able to create new palettes and add commands/brushes to existing palettes  etc... BUT am unable to further organize/customize (While holding shift key) and arrange them to where I want.  It effectively makes custom palettes useless as they cant really be customized.  Please see video at link below.

Anyone have suggestions or experience with this issue?
