Contact General Info Disappeared

So this is a new one for me. I am getting ready to run our fall club shipment and noticed this today…

All the these club members no longer have any info under the General tab in their accounts. Only their email addresses. Everything else is fine (cc info, shipping addresses, clubs, purchase history). None of them have cancelled.

It has only happened to these mixed club members. Some have made changes to their accounts for the shipment and some haven’t.

Anyone else had this happen?
