Creating/Editing/Admin Bar Incorrect

I have recently came across an issue with a 7.50 Drupal site. I am using Seven 7.50 as the Administration theme. It was showing duplicate Admin bars, but i resolved this with disabling the toolbar module. The issue now is when i edit a page or open an interface to do anything the “X” to close the interface is missing. It seems as if the page is displaying wider than my screen, but zooming the screen in and out does nothing.

Drupal version:
