Links issue in Category Archive

Hi there,

I have made changes to “.entry-meta a”, “.entry-utility a”, “.entry-content a”,”.entry-summary a” and they all took effect in every pages initially but after I have installed WP e-commerce, every pages remained the same except for the Category Archive page where the links such as entry date, author name, category, leave a comment and continue reading are not taking up the changes. Please note that there is no issue at all on changes to hovers on them. Could anyone please help me? Many thanks

The following are the related CSS changes made:
.entry-content a,
.entry-summary a{
color: #888;
text-decoration: none;
font-size: 12px;
}

.entry-meta a,
.entry-utility a {
font-size: 11px;
text-decoration: none;
}
