bbPress.org

Hi!
PLease, help me to fix this!

I don’t understand: bbpress in my site uses template page.php. In this template we have:
<?php get_template_part('inc/page-title'); ?>.
In /inc/page-title.php we have:
<?php elseif ( is_page() ): ?><h2><?php echo alx_page_title(); ?></h2>

But in http://muzl.it/forums/ we have title
<div class="page-title pad group"><h2>Темы</h2></div>
and in http://muzl.it/forums/topic/lorem-ipsum/ we haven’t title:
<div class="page-title pad group"><ul class="meta-single group"><li class="category"></div>

How to fix it?
