do you have the bbp toolkit plugin active ?

The reason that it is dequeued is that it was built that way by the software company that built our theme. This, I assume, was so that the forum would look like the rest of our site.
My issue, by adding the ($args) arguments (to that snippet of code) and by removing that one line of CSS has now resolved this issue completely.
Thank you!

		Hey Guyes,
This issue because you are using this function [bbp_list_forums] in [loop-single-forum.php] with old (2.5.0) default args array in your active theme.
You must use [bbp_get_forum_id()] in function’s args, So try to find this function inside the active theme and change the value of the [forum_id] argument.
bbp_list_forums( array(
    'before'            => '<ul class="bbp-forums-list">',
    'after'             => '</ul>',
    'link_before'       => '<li class="bbp-forum">',
    'link_after'        => '</li>',
    'count_before'      => ' (',
    'count_after'       => ')',
    'count_sep'         => ', ',
    'sep'               => '',
    'forum_id'          => bbp_get_forum_id(), /* Fix for bbPv2.6.3 */
    'show_topic_count'  => true,
    'show_reply_count'  => true 
) );
Hope it helps.
