Bug – Paid listing extended without payment

Hello there,

I’m facing an issue with my new website. For paid user which don’t have an automatic renewal set, they can currently renew their listing without completing the renewal process and without paying.

Here are some screenshots:

Step 1 – User is logged into his account: http://prntscr.com/eepezn
Expire date is March 3, 2017 (2 days left)

Step 2 – User has clicked on “Renew listing”: http://prntscr.com/eepfnj

Step 3 – User has clicked on “Review Your Listing”: http://prntscr.com/eepgnt

Step 4 – User has clicked on “Checkout to Renew Now”: http://prntscr.com/eephda

Step 5 – The user close the window and do NOT proceed with Paypal payment. He goes back to his dashboard: http://prntscr.com/eepi5h

The expiring date is now March 1, 2018 (1 year left) and it has been extended of one year without proceeding with the payment…

How is that possible? How can we fix this issue?
