Acf field edit

Hello, guys.
I inherited a project in my company, and noticed that most pages use Acf. my problem is that in some pages, like the one show, the section only appear in the code, not in my wp Admin panel, so i’m lost in how to cahnge the data on these pages. Like the example, in the code it shows like:

<section class="section section-contato-2">
	<div class="container">
		<div class="row">
			<div class="col-md-12">
				<h2>Contato e localização</h2>

			</div>
			<!-- /.col-md-12 -->
			<div class="col-md-6">
				<?php
				if( have_rows('unidades', 60) ):
				while ( have_rows('unidades', 60) ) : the_row(); ?>
					<h3><?php the_sub_field('titulo', 'option');?></h3>
					<?php the_sub_field('descricao', 'option');?>
				<?php endwhile; ?>
				<?php endif;?>
			</div>
			<!-- /.col-md-6 -->
			<div class="col-md-6">
				<?php echo do_shortcode('[contact-form-7 id="58" title="Contato"]');?>
			</div>
			<!-- /.col-md-6 -->
		</div>
		<!-- /.row -->
	</div>
	<!-- /.container -->
</section>

But in my panel, i’m unable to find this subfield titulo and descriçaõ to alter.
Can anyone enlighten me on the relation between code and the plugin, and how to find and change the info?
