[Forminator Pro] Forminator Custom panel failure

Under: Edit>Appearance>Colors>Custom…
When I select one of the drop downs (IE: Form Container, Response Success, etc.) the embedded options panel doesn’t display. I maintain the WP base elements to the top and left, the grey background color from the WPMU DEV page, and the Made with (heart) by WPMU DEV footer. The footer appears directly under the small WP header bar. Any ideas?
