Easy Profile extends Joomla user management (not replace). This tabs come from a user plugin called "Easydiscuss Profile", it add EasyDiscuss Fields in Registration,edit profile and profile page. I'm sorry but Easy Profile can't manage this plugin, so you have 2 options:
1. Disable this plugin
2. If you want EasyDiscuss fields in Registration and Edit Profile but you do not want it on profile page then you need to make some customization for this plugin. For example you can remove this output by adding following code at line 96 in file /plugins/user/easydiscussprofile/easydiscussprofile.php

if(JFactory::getApplication()->input->get('option')=='com_jsn') return true;
