Ultimate Branding Insecure Content Can't Get Padlock

When I put a custom admin bar logo in place using Ultimate Branding, I cannot insert from URL and specify https. So the content is called insecurely and prevents me from getting a green padlock. I searched the database in PHPmyadmin and can’t find the instance to edit that is specified at http://www.whynopadlock.com Is there a workaround for this?
