Slider overlay not viewing properly

Hi,

How do I get the slider image to show full width as it was before? For some reason its changed but I can’t work out where to correct this? I’m still learning/newish to wordpress. As you will see from the website link its now contained and also goes behind some of the content. Before it ended before the content.

Thanks
Mark
