Recurring payment not updates in opencart recurring order history

I am selling digital products and have to open each lesson when recurring payment completes. I created a recurring profile with 11days payment($5/every day) and basic product cost is $10.... I am using sandbox and set IPN url successfully. Order is creating fine and showing in admin->sales->recurring orders... Till this step everything is fine but every day transaction not updating/showing in admin anywhere ? I have to put condition for open lesson on the basis of each recurring payment.

OC version. Wrong forum section.
