You have some serious nesting issues in your code that I’m not sure how to fix, but adding some whitespace to show the nesting makes them more visible.
<div class="minutes">
<?php
// check for rows (parent repeater)
if (have_rows('ma')):
// loop through rows (parent repeater)
while (have_rows('ma')):
the_row();
?>
<h2>
<?php
if( get_sub_field('ma_department_name') ):
the_sub_field('ma_department_name');
endif;
?>
</h2>
<?php
// check for rows (sub repeater)
if( have_rows('ma_meeting_year') ):
// loop through rows (sub repeater)
while( have_rows('ma_meeting_year')):
the_row();
?>
<ul>
<button class="accordion">
<?php
if( get_sub_field('ma_year') ):
the_sub_field('ma_year');
endif;
?>
</button>
<div class="panel">
<li>
<?php
// check for rows (sub repeater)
if( have_rows('ma_files') ):
// loop through rows (sub repeater)
while( have_rows('ma_files') ):
the_row();
if( get_sub_field('ma_date') ):
the_sub_field('ma_date');

if( get_sub_field('ma_title') ):
the_sub_field('ma_title');

endif;
$file = get_sub_field('ma_agenda');
if( $file ):
$url = wp_get_attachment_url( $file );
?><a>" target="_blank">Agenda</a><?php
endif;
?>
</li>
</div>
</ul>
<?php
