You can show certain profile fields on member directory by using the next function :
Note : You will have to adapt this function for your needs by changing the name of the fields Location and Specialization from example.
The function will have to be added in wp-content/themes/kleo-child/functions.php
If you have problem viewing the snippet copy code directly from here : http://pastebin.com/raw/QByiEAhH
Examples :
$location = bp_get_member_profile_data('field=Location');
$specialization = bp_get_member_profile_data('field=Specialization');
field=Location represents name of the field that we need to show in the member directory
field=Specialization represents name of another field that we need to show in the member directory
And so on..
