IE is inserting a space above a content container in a CSS website

Hi, going around in circles trying to resolve. I think it is due to a quirk in how IE reads positioning of CSS elements. I attach the HTML file for one page, (all but Home page are created from a single template) built in Dreamweaver CC. The webpages display fine in Firefox, Chrome and Opera, but,  IE inserts a space above the main body content container set as an editable region.

If I change the relative positioning setting for the menu buttons, IE will display correctly, but, Chrome pushes the content below the bottom of the menu.

The menus code (which is created from a Dreamweaver extension), sit in a div which sits inside the div 'Sidebar' container. Is this what causes IE to misplace the body content container ??

View this page http://www.destinationdata.co.uk/sportpathways/spl-privacy.html in IE and Firefox. The Breadcrumb and all content below is pushed downwards only in IE. The Breadcrumb line should be level with top of the 'Home' Button as it is in other browsers.

The Breadcrumb line is at the top of the editable 'container'

The attached files are before cleaning up. I did an earlier clean but it did not resolve.
