To determine if the issue is in your theme, try switching momentarily to a WP theme like 2013.
You’ll need to copy members-loop.php to a buddypress folder in that theme.

You can only echo the data if it exists.
Try:

$your_name = bp_get_member_profile_data( 'field=Your Name' );
if ( $your_name != false ) 
   echo $your_name;
