Emails indicating a sale, but no order listed

Hello:
I have been getting several emails a day about orders from my website, there is no order showing in my admin and also nothing has shown up in my pay pal account. I use website payment pro with zen cart 1.3.8a, this system work a few days ago but now I get emails that say the person wasn't logged in. I will paste a series of emails below with identifying info hashed out.

cart contents is not all virtual or customer is not logged in ... therefore
