Cheque number sequence getting picked in multiple numbers when making one payment

In the oracle 12.1.3 instance, when making payment through the 'Fund Disbursement' responsibility, through a newly created cheque book which has 50 cheque leaves, all 50 payment document numbers are getting picked.

For example, the new cheque book is created with 50 leaves and the first cheque number is used to process a payment through fund disbursement responsibility.

Once the payment is processed, it shows all 50 leaves are being picked.

When inquired cheque number 1 to 50, all leaves showed as being used.

However, when we tried making a payment from a cheque book that has already being used this issue did not come.

This is only when using a new cheque book, for a payment processed through fund disbursement responsibility.
