"Author" meta box for the Custom Post Type

The “Author” drop-down is missing in the post editor for the “WP Job Manager” Custom Post Type, so I can’t reassign a job listing to another active WordPress (admin) author.

I’ve tried adding ‘author’ to the supports array for the custom post type, like this:

'supports' => array( 'title', 'editor', 'custom-fields', 'author' )

That’s on Line# 188 in the file “class-wp-job-manager-post-types.php… yet the author meta still doesn’t show up. And yes, I’ve looked under the “Screen Options” tab to make sure it’s not unchecked. 😉 but it doesn’t even show up there as an option.

Am I going about this the wrong way, or missing something else? Thanks everyone!
(Latest WordPress 3.6.1 and latest WP Job Manager 1.2.0) No other author based plugins installed.
