Hi, for continue this issue (https://megadrupal.com/forum/theme-support/delphinus/3794)

I browsed the internet and I found out the bug is actually because you use 

<?php print t('Description'); ?>
<?php print t('Additional INFO'); ?>
<?php print t('Review'); ?>

according to Drupal forum (https://www.drupal.org/node/2332467) , you should use

print render($content['body']);

Please help to fix it.

Thanks.
