did you get a output when you use something like this? :
<?php
// check if the repeater field has rows of data
if( have_rows('address_details') ):
// loop through the rows of data
while ( have_rows('address_details') ) : the_row();
// display a sub field value
the_sub_field('address');
the_sub_field('author');
endwhile;
else :
// no rows found
endif;
?>
