[Membership 2 Pro] Membership sending old invoice instead of new invoice to subscriber

We have a member who had a membership from 2016-2017, then bought another membership recently. Instead of receiving an invoice for the new membership, she received her original invoice, w/ the 2016-17 dates and info.

I confirmed this by seeing the invoice she was sent, as well as looking here: /wp-admin/admin.php?page=membership2-billing&show=logs&invoice=6398
