user paid twice for the same certificate? #1342

So I was looking at the data for these two orders and here are things that I could identify so far:
I'm not sure if this was expected for data that was migrated from MM but I think if we were to look more we need to check how we migrated that data and check the cause within MM. |
Ok, since these are historical MicroMasters orders, I'm not going to worry about it too much. The user probably made multiple exam attempts, which we could determine by examining their exam authorizations and grades in MicroMasters. |
Not sure how this happened, but it seems like we have two fulfilled orders for the same course:

https://mitxonline.mit.edu/orders/receipt/6249
Was perhaps one of them refunded and the database wasn't updated?
I noticed this when looking at https://bi.odl.mit.edu/queries/1189 where it lists two certificates for the same course run.
