It looks like you were able to get this resolved with someone via chat earlier -- glad it was sorted out.
For others who happen to experience this, please check to see if you add an image as your background under Page Settings > background, links footer. If you have "Image" selected, Sitebuilder will use that image and tile it as your background. You can just choose "color" instead, if you do not want this to be the case.
My image duplicates multiple times and I cannot get it to reduce to one image.
Another problem is the web page is almost ready to publish but after a preview, the words overlap each other in two of the pages, which is not the case after I "save" in the build portion of web design.
