[3.0] Unwanted border (line) on category archive page

There’s an extra border when using category header style2, right on top of the top posts grid (grid style 2). It extends to full width (tested only in Chrome atm). You can get rid of it with the following CSS rule:

.td_category_top_posts_style_5 .td-category-header {
border-bottom-width:0;
}
