I have a problem related to 'mailings'. When I create a new mailing and select a group (for example, 'current members') in 'Recipients' then it is not showing all recipients. For example, I have 5681 total contacts, 67 of which are in 'Current Members' group, but after selecting this group in mailing it is showing only 4 recipients. I have checked there are not any blocked contacts and there are also not "Do Not Call" for any contact.
I am using following versions
CiviCRM Version 4.7.17 Wordpress Version 4.7.3
