Hello,

It's actually not "showing up twice" but it's actually for different purposes. The one at the top subscribes you to the "site wide" feeds. The one at the bottom on the same line with Featured allows you to subscribe to only featured entries. If you want to remove the bottom one, edit the file /components/com_easyblog/themes/default/blog.featured.php and at line 18 remove the codes below:

		<?php if( $system->config->get( 'main_rss' ) ){ ?>

		<a href="<?php echo  EasyBlogHelper::getHelper( 'Feeds' )->getFeedURL( 'index.php?option=com_easyblog&view=featured' );?>" title="<?php echo JText::_('COM_EASYBLOG_SUBSCRIBE_FEEDS'); ?>" class="float-r ico link-rss"><?php echo JText::_('COM_EASYBLOG_SUBSCRIBE_FEEDS'); ?></a>

		<?php } ?>
