[Plugin: WooCommerce] Checkout Page Issues

In Internet Explorer (Not Chrome or Firefox), when I get to the Checkout Page, it throws all the widgets to the bottom (like a mobile view) and makes the actual checkout take up the full page width. Where it says “Your Order”, that for some reason changes to show my entire home page, instead of the items someones buying and the “Place Order” button. When I put the “[woocommerce_checkout]” tag on another page and view that directly, it says as it should, widgets on the left and the normal “Your Order” section but as soon as I go to WooCommerce settings>Pages and update the Checkout page, when I look at it again, its messed up.

Its very weird and something I’m not sure if I’m explaining thoroughly and well enough but its keeping people from checking out so I’m not really sure what to do. Any help would be great, thanks!
