Does not show in leading topic

I am using add_filter( ‘bbp_show_lead_topic’, ‘__return_true’); to give my forum a better look. This splits the main topic from the replies.

but then the plugin does not show in the leading topic. It only show up in the replies

Do you have any solution for this problem?

Monique
