mmm Yes, you will need to duplicate the FAQ template

You seem to have CSS conflicts with your Joomla Template or with the CSS of other extensions.

(a) You can correct this by adding specific CSS rules in a CSS file of your Joomla template
or
(b) Duplicate the FAQ template which will give you more control, since besides changing the CSS you can change also change the HTML of category_items.php too.

By changing the HTML you can add more template positions into the category_items.php too, and also adding CSS class for your CSS changes.
