joejozwowski on "Child theme not incorporating Child Style.css"

I've done MANY child themes in the past, but this one is currently stumping me.

I took a look at the header of the style.css of the parent and this is what I got:

/*
Theme Name: Parent Theme
Theme URI: http://www.theme-site.com
Description: This is the parent theme
Author: Theme Author
Author URI: http://www.theme-site.com
License: GNU General Public License v2 or later
License URI: http://www.gnu.org/licenses/gpl-2.0.html
Version: 1.0
@package Top10
@since Top10 1.0
*/

And here is MY child style.css

/*
 Theme Name:   Top 10 Child
 Template:     top10
*/

Wordpress Codex says those are the only two lines "really" needed to link the parent and the child. I've never seen the @package or the @since tags in the header before, and I feel they may have something to do with my dilemma
