Truncated Post Titles on Thumbnails

My Post titles as Thumbnails are being trimmed, is there a way to prevent this, i.e. show the full title always?

Below is the code I am using, am I missing a param perhaps?

yarpp_related(array(
			// Pool options: these determine the "pool" of entities which are considered
			'post_type' => array('talks'),
			'show_pass_post' => false, // show password-protected posts
			'past_only' => false, // show only posts which were published before the reference post
			'exclude' => array(), // a list of term_taxonomy_ids. entities with any of these terms will be excluded from consideration.
			'recent' => false, // to limit to entries published recently, set to something like '15 day', '20 week', or '12 month'.

			// Relatedness options: these determine how "relatedness" is computed
			// Weights are used to construct the "match score" between candidates and the reference post
			'weight' => array(
				'body' => 1,
				'title' => 2, // larger weights mean this criteria will be weighted more heavily
				'tax' => array(
					'talk-tags' => 3,
					'topic' => 2
				)
			),
			// Specify taxonomies and a number here to require that a certain number be shared:
			/*'require_tax' => array(
				'post_tag' => 1 // for example, this requires all results to have at least one 'post_tag' in common.
			),*/
			// The threshold which must be met by the "match score"
			'threshold' => 5,

			// Display options:
			'limit' => 8, // maximum number of results
			'order' => 'score DESC'
		),
		$reference_ID, // second argument: (optional) the post ID. If not included, it will use the current post.
		true);
