I have done a test checkout on your website and could see that Auto Return feature is turned off on your sandbox account.

Auto Return is turned off by default.

1.To turn on Auto Return

2.Log in to your PayPal account at https://www.paypal.com.

3.The My Account Overview page appears.

4.Click the Profile subtab.

5.The Profile Summary page appears. Under the Selling Preferences column, click the Website Payment Preferences link.

6.The Website Payment Preferences page appears, as shown below.

7.Under Auto Return for Website Payments, click the On radio button to enable Auto Return.

8.In the Return URL field, enter the URL to which you want your payers redirected after they complete their payments.

Also, note that Auto Return Feature will not work if the Payment is made with Debit or credit card. You need to manually click in "return" link to get re-directed to your return URL.
