Hi,
I checked the page and it is a CSS problem.
Your template makes an aggregation of the different CSS file required and it compress it too.
The problem is that, in this page, the HikaShop CSS content is not there. Maybe it's a cache problem of the template, I can't be really sure.
But I am sure that there is not the HikaShop CSS content in the page and that's why the control panel can't display the icons ; they are defined in the HikaShop CSS.
Please check the "CSS compression" and "cache" features of your template.
