Redirection to Payment Page After Successful Purchase

Hi,
When a transaction is successfully completed using Pesapal. The customer is redirected to the payment page instead of the order details page as the other payment methods do. However, the order is reflected both in woocommerce orders and Pesapal merchant account and can be processed without any problems. This happens when using both the demo.pesapal.com account and
the pesapal.com
Thanks.
