[Plugin: WP Single Post Navigation] Filter applied, now doesn't show post title

Hi,

I’ve added both filters from your FAQ page for modifying the tooltips.

wpspn_filter_previous_post_tooltip and wpspn_filter_next_post_tooltip

The text before the colon changes as per the filter but the post title disappears.

Any suggestions?

Thanks, Rod
