Custom Heading Duplicating Image After Highend Theme Update

Grownbyyou.com uses Custom Heading as its header. Prior to most recent Highend Theme update, it worked properly (the image was shown as a cropped banner that moved up and down as the user scrolled). Now, it places a second full-width, full-crop static (duplicate) of the banner image above the actual banner image. This is consistent on all Custom Headings throughout our website. Please advise.
