Horizontal Scrolling - Can't edit all elements

Hi there i am having great difficulty editing the content all cards’ content within a horizontal scroll. There are five cards with content and I can scroll all the way to the right but there are further elements to the left that I just cannot reach. However if i toggle preview i can see all elements and the horizontal scrollbar does exactly what it should (this is a template that i bought) Does anybody have some wisdom that they can share please? below i’ve pasted an image and website. the blue arrows on the image identify where i am trying to scroll - any help is appreciated

here is a link to my page:
