Help With Icons – Please!!!

Hi Community,

I am in the process of sorting out a website to sell all my beats. I have set up the digital download on the frontpage but alas it works perfectly except it doesnt display the icons on the tracks. I cant see them but I imagine they are the shopping cart icon..

It is such a simple thing but makes the site look so bad without it. BTW the prices on there and tracks are for example only at this stage just so I could check functionality.

Has anyone else had this problem and how do I fix it please please hahah
