Thank you for your response. As I mentioned, we have tried disabling all the plugins and have subsequently done a full re-install of the theme but are still running into the issue. To reproduce the issue you probably will need to refresh the page a couple times, it seems completely random. One thing that we have noticed is that if, once the page is loaded in the incorrect format, you resize the browser window then the slider loads properly and the page is formatted correctly. I assume this is an issue with the slider plugin. Are there any known issues with the slider plugin or its implementation into this theme that would cause this?
