Most themes contain either a “single.php”, “post.php” or “page.php” file within /wp-content/themes/bamboo-10/ (In your case.)
Usually within those files there is a line of code which will create the Author Credit link/name slot. You’ll need to look in those files to find the line of code which makes that line appear. The codes will be useful for this. So this should be a fairly easy modification to the theme files.
