If I understand correctly, you made a payment to a wrong account and the amount was credited back to your bank account. 

If that is the case you have 3 options: 
1: simply don't import those 2 transfers, as it has no impact on the running balance by the end of the month
2: reconcile both transactions with another account (a "corrections" account), since the bank suspense account by default does not allow reconciliation.
3: temporarily turn on reconciliation on the bank suspense account and reconcile the 2 transactions from General Ledger

And ask your accountant for advise before you do any of the above ;-) I am not an accountant...
