Author of post not working with custom post type

Hi,

I converted a view posts to a custom post type. These posts have a specific author. These authors are exposed in the theme by <?php the_author_posts_link(); ?> This works perfect. But when I look under users on the admin side, WordPress does refer any post to these authors. Which is strange because under edit posts the author is the author of the post. This error gives me problems on the author theme template. I can’t make a query to show only the post from a specific author. Does anyone have a solution for this strange problem?
