Paypal checkout - user says he did only one transaction

[karhong]

Hi,

I would like to ask regarding the success returned data as below.

User claimed that he did only one transaction, but from the data returned, I can see the PAYID is different.

I'm not familiar with paypal checkout returned data, just wondering is this a bug [which paypal really fire twice, and charged member twice] or user's the one did the transaction twice ? I don't think my program is the problem as this is fired from paypal right? 

Both transaction are 7 minutes difference.

Thanks in advance.
