Hi @jarv81178
You need to use this code <?php the_title(); ?>
to show the post object title. It should be like this:
if( $post_object ):
echo 'xx';
// override $post
$post = $post_object;
setup_postdata( $post );
the_title();
echo 'Conference Streams: '.get_sub_field('conferencestream');
wp_reset_postdata();
endif;
Also, please make sure that you set the “Select multiple values?” option to “No”.
I hope this helps.
