Unable to close Payables period due to unaccounted transactions (payment clearing)

Good day. I ran into an issue in closing the period of Jan-13. Apparently there are a couple of Payables checks that were generated in Feb-13 and cashed in Feb-13, however, when the bank statement was imported into the Cash Management module, the G/L date was imported incorrectly with Jan-13.

Can we change the GL Date for the bank statement to the correct date in Feb-13 and will it reverse the incorrect Jan-13 entries? If that will work, I am then assuming that I would be able to successfully close Payables for Jan-13.

The error log states: "Cannot Account for clearing of xxxxxx Account bank account's check number xxxxxxxxx because a prior event is NOT accounted."
