Document Widget and IOS

Hi,
I have added two document shortcode widgets to one of my training pages. They work perfectly on my PC Laptop. When it comes to my Ipad and Iphone, the Titles show on the right sidebar where the widgets are but the documents are not showing up. Just blank. You can see at http://motorsdrivestraining.com/training/abb-training/

Any ideas?
