you’ve lost me now 🙂
The key line that does the reference is
<a href="<?php bbp_topic_permalink($topic); ?>"><?php bbp_topic_title($topic) ?> (<?php bbp_topic_last_active_time($topic); ?>)</a>
This translates as
<a href="[topic link]">[topic title] ([date])</a>
which makes both the topic title and the date a single clickable link and the code shows 3 of these.
I’m not really sure what you are trying to achieve – I had thought you wanted 3 clickable links on both title and date, which is what the above does.
If you don’t want the date clickable, then do
<a href="<?php bbp_topic_permalink($topic); ?>"><?php bbp_topic_title($topic) ?></a> (<?php bbp_topic_last_active_time($topic); ?>)
