Partial Import of the users from AD

Partial Import of the users from AD

HI,
 
I am able to import the users from AD but the number of requesters imported are not matching with the number that is shown in Admin->Requesters tab.
 
Eg: When i import the users from AD, the output shows that it has imported 1400 users whereas when i go check the Admin-Requesters page it shows only 700 odd users.
 
Please find the screenshots in the attachement.
 
Regards
VS
