Icon box is linking to 'undefined' even when link is set to none

Hi there,

Having a slightly strange issue. On the page I linked (in private below) you can see there are three icon boxes in the ‘Our Solutions’ section.
When I click on either the icon or the box itself, it loads an ‘/undefined’ link.
When I check the page design, there is no link applied for these icon boxes.

Is there some other event listener picking these up somehow?

Cheers,
Mike
