Applicant number range-NUMAP

Friends

We have configured the recruitment and the NUMAP feature is internal starting from 1.

We have performed the initial entry of basic data action, applicant number is generated with 1. but the current number showing as 5 in the number ranges

Again we have performed the same action, then the applicant number generated as 6 and the current number status showing as 10

But it should be generated sequence wise like 1, 2 3 etc why system creating in such a way

Regards
