bbPress Back to discussions links to home

Hi,
I installed bbPress on Highend and noticed the “Back to discussions” text on top of each topic is linking to home page of the site instead of the forum index/topics.

I checked the demo forums on your site which also has the same issue, you can refer this link: http://hb-themes.com/themes/highend_wp/forums/topic/test-topic-three/.

Any thoughts how to change it like this forum?

Thanks,
Naga
