Template is lacking the CSS to properly format the icon display. You can adjust the menu links CSS within the your CB Blogs template CSS file. The below is the CSS you'd need to review.
Code:
/* CB Menu */
ul.cbMenuULlist li.cbMenu_UE_MENU_CB_BLOGS a {
background: url(images/icon-16-blogs.png) no-repeat 2px 2px;
display: block;
}
ul.cbMenuULlist li.cbMenu_UE_MENU_CB_BLOGS a:hover {
color: #FFFFFF;
background: #1E5FA2 url(images/icon-16-blogs.png) no-repeat 2px 2px;
}
