I figured out the solution. I was to use array_column which helped me focus on that single column of information.
<?php if( get_field('degrees') ) {
while ( have_rows('degrees') ) : the_row();
$array[] = get_sub_field('degree_select');
endwhile;
$foo = implode(', ', array_column($array, 'label'));
echo $foo;
}
?>
