I assume it is an error. We are working on a fix but basically when we switched to Xenforo for our software, some of the older PayPal subscriptions don't automatically sync up with your profile. We have an outstanding Treasurer @Adam who can get this fixed for you. I need to talk to him anyways so I'll give him a call and work on correcting this for you ASAP.
Holy Cow! It's from back in March. I've processed them several times since then. I somehow must have missed this one.
I'm sorry. Refund is forth coming and I will cancel that old subscription as well.
