Class is not correctly adding by this plugin

I am using this plugin in my page like

    <?php
    echo do_shortcode('[site_reviews_form class="box-shadow-commn" assigned_posts="post_id" hide="title,email,terms"]');
    ?>

Before the 7.x.x updates, it was working fine. But now, it add class like –

<div class="glsr glsr-default glsr-ltr" id="glsr_fb4b17d1" data-from="shortcode" data-shortcode="site_reviews_form" data-assigned_posts="25448" data-class="box-shadow-commn" data-hide="[&quot;title&quot;,&quot;email&quot;,&quot;terms&quot;]"><div class="glsr-form-wrap">

Exact Issue: It added data-class=”box-shadow-commn”
Expected: class=”box-shadow-commn” and other classes by this plugin
