I'd be happy to help you with this, although I am not seeing a difference between the two images you posted. Where is the white bar located on the sent email? Also, what email client program are you receiving the email in? If you could please send us an email with your username, the campaign you are having issues with, and a reference to this post to social_support(at)constantcontact(dot)com we can look into this for you!
