I had the same thing happen, I didn't "renew" at all yet, did I have an auto renewal setup or something?
I planned to renew but it did it without even asking me.
It is a PayPal thing, I get it..
It's actually cool, but I wasn't aware it did that.
But I "think" it's somehow setup that way by the "BRS" no? as a Subscription, not just a payment?
