JSON Widget Configuration Not Working (Visual TOC)

Jenna.S.54

Hello - I have entered in custom widget configuration for the Visual TOC widget but the changes are not showing. I have no idea what to do to resolve this, please advise?
The attached screenshot shows I'm trying to change the header colour to #009990 but the header colour remains the default blue.
