Calling an image using ACF Select Field Type

Question

I am running Advanced Custom Fields on a Wordpress build and I added a Select Field Type to image attachments. The Field Name is image_category and I have three selections: top , middle , bottom . These images will be called around multiple parts of the site in different iterations. Some sections have multiple images that I want to show together but should be ordered randomly. In the bottom example, I am only calling one image that has the category bottom selected. This doesn't seem to find the image however, could this be a field issue? I haven't figured out how to call these images using the $get_field() function which in my head, seems easier than taxonomies? Any help is much appreciated!

    'orderby'           => 'rand',
    'tax_query'         => array(
        array(
            'taxonomy'  => 'image_category',
            'field'     => 'slug',
            'terms'     => 'bottom',
            ),
        ),
    );
$banners = new WP_Query( $banneradverts );

while ( $banners->have_posts() ) : $banners->the_post();?>
<section id="bottom">
    <div class="bottom-image">
        <?php echo wp_get_attachment_image( get_the_ID(), 'full'); ?>
    </div>
</section>          
<?php endwhile;     
wp_reset_query(); ?>

<?php
$args = array(
    'posts_per_page'    => 1,
    'post_type'         => 'attachment',
    'post_status'       => 'any',
    'orderby'           => 'rand',
    'meta_key'          => 'image_category',
    'meta_value'        => 'bottom',
    );
$the_query = new WP_Query( $args );
?>
<?php if ( $the_query->have_posts() ) : ?>

<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<section id="bottom">
    <div class="bottom-image">
        <?php echo wp_get_attachment_image( get_the_ID(), 'full'); ?>
    </div>
</section>          
<?php endwhile; ?>
<?php wp_reset_postdata(); ?>

<?php endif; ?>
