Too Much HTML On Page

Running through some optimization for our site, I notice this plugin loads a lot of CSS code at the top of the page within;

<style id=’wpdiscuz-frontend-css-inline-css’ type=’text/css’>

Why is it not loading via a CSS file?

All together this amounts to over 700 lines of code at 16,000+ characters. Here is an example:

#wpdcom .wpd-blog-administrator .wpd-comment-label{color:#ffffff;background-color:#0085FF;border:none}#wpdcom .wpd-blog-administrator .wpd-comment-author, #wpdcom .wpd-blog-administrator .wpd-comment-author a{color:#0085FF}#wpdcom.wpd-layout-1 .wpd-comment .wpd-blog-administrator .wpd-avatar img{border-color:#0085FF}#wpdcom.wpd-layout-2 .wpd-comment.wpd-reply .wpd-comment-wrap.wpd-blog-administrator{border-left:3px solid #0085FF}
