Hello Paul,
Thank you for your question about your subscription. This is showing correctly now. For some reason, the PayPal notification of your extension didn't get recorded, so I updated it manually.
I hope this has been explained to your satisfaction. Thank you for writing in, and please let me know if you have any other questions.
