Ultimate Branding Plugin error message

I am getting a browser error message due to some broken code in the Ultimate Branding Plugin and it seems to be interfering with the ability to drag and drop the menu items in the Admin Menu section.

Here is the message:
AG Custom Admin caught a JavaScript on your site:
TypeError: 'undefined' is not a function (evaluating '$('.ultimate-color-field').wpColorPicker()')
