Back/Forward Buttons in Browser causes multiple drawings

I'll try to describe to the best of my ability. So what happens is if I click on any link from the page with the datatables then click back, it seems to draw another part of the datatable on top of the datatable. Clicking back/forward multiple times, creates multiple partial datatables on top of the datatable.

Here's the link to the page I'm seeing:
