Page Category names

Hello,
I have a problem with displaying page category names properly.

For example I have “Documents” and “News” categories.

When I go on a category page, let’s say “News” the category page’s title is “My pages” instead of “News”

On the single private page the title displays just fine.

Is it possible to have the category’s name displayed ?

Thanks

UPDATE:
I noticed the category.php file in my theme
The part wich displays the title is as follows :

<h2 id=”category-title” class=”archive-title”>
<?php printf(__(‘Category Archives: %s’, ‘airballoon-lite’), ‘<span>’ . single_cat_title( ”, false ) . ‘</span>’); ?>
</h2>

Any suggestion ?
