BP Social Theme - Problem with layout in IE


I have a problem with layout in Internet Explorer. There are only 2 pages which are displayed correctly. Rest of them, if you scroll down the page, there are 5 widgets which are displayed next to the right sidebar. I've noticed those widgets are from BBPress sidebar. But how come they are duplicated on other pages?

Any thoughts? I have tried to disable all plugins and can not seem to find a conflict that is effecting ie.

Thank you.
