Header overlay problem

Hi – We’ve been having an intermittent issue with the underlying image under the header. Most pages have a wood texture under the transparent menu. This is created by a 150px spacer with a background image set to cover. The other pages behave as they should but every so often the Home page spacer will appear below the transparent menu leaving the header completely white as the text and logo are white. I’m somehow able to fix it for awhile but it comes back.

Very bizzare. I matched the spacer effect settings with the other pages and it seems to have corrected itself again.. but for how long is unknown.

Thanks.
