Okay, I see the problem now and I am able to reproduce this issue locally as well. It has something to do with your current "Home" menu setup. It is causing the category to not inherit the values correctly. I have logged this into our issue tracker.
Temporarily, what you could do to get rid of this is to edit the file /components/com_easyblog/themes/wireframe/blogs/categories/item.php and remove the codes at line 46 - 52,

<?php if ($this->params->get('category_subscribe_rss', true) && $this->config->get('main_rss') && $privacy->allowed) { ?>
<span class="eb-category-rss">
<a href="<?php echo $category->getRSS();?>" title="<?php echo JText::_('COM_EASYBLOG_SUBSCRIBE_FEEDS'); ?>" class="link-rss">
<?php echo JText::_('COM_EASYBLOG_SUBSCRIBE_FEEDS'); ?>
</a>
</span>
<?php } ?>
