The list comes from a K2 Module.
You can use the Advanced Module Manager extension (
extensions.joomla.org/extensions/style-a-design/modules-management/10307) an choose from the module's settings not to show in the item pages
or
you can add this code to the index.php of your template in place of the current module position code.
<?php $view = JRequest::getCmd('view'); ?>
<?php if($this->countModules('Your_module_position) && ($view!='item'): ?>
<jdoc:include type="modules" name="Your_module_position" style="nu" />
<?php endif; ?>
You can advise your template provider/developer in order to help you with this as well.
