You have the define the section:

{section name=field loop=$extra_fields}
{if $extra_fields[field].active eq "Y" && $extra_fields[field].field_value}
{$extra_fields[0].field_value}
{$extra_fields[0].field}
{/if}
{/section}

You'll just need to adjust/add/remove the

{$extra_fields[0].field_value}
{$extra_fields[0].field}

part to show the extra field you want to display
