How do I edit the page layout of wikis?

I'm using this template here: that comes with several page layouts. Every wiki I create uses the standard page layout I define (full width, left side bar, right sidebar). Problem is, the wikis always show the blog sidebar instead of the right or left sidebar (called in with <?php get_sidebar(); ?> instead of <?php get_sidebar('right'); ?> or <?php get_sidebar('left'); ?>:wink:. Where can I edit the wiki page template?
