Can't see all unpaid invoises in "invoice payment"

Can't see all unpaid invoises in "invoice payment"

Hi!
I have one inconvenience in using zoho invoices. I have one customer with a lot of counts of unpaid invoices (at this moment he has 109 unpaid invoices). When this customer pay for his overdue invoices I go (in new version of the site) to Contacts->choose him-> new transaction -> invoice payment. On this page of the site I see his unpaid invoices. But inconvenience is that I can't see ALL his unpaid invoices (at this moment I see only 99 unpaid invoices instead 109). Also I can't sort the list of his invoices by date of creation to see the oldest - exactly invoices that has paid my customer.
So I switch to old version of the site and there I see all 109 unpaid invoices.. 
Help me please, I do something wrong or it is a programm error?
Thank you in advance.
