Twitter and Pinterest displayed twice

Hi,

On the home page of matterism.com, the twitter and pinterest buttons are displayed twice. I managed to style display:none; the twitter button, but I cannot do the same to the pinterest button since it is styled display:inline-block !important;

Can you help me with this? Thank you.
