I have reset my bank statement but the unresolved amount is the same as it was prior to doing the reset. What could I have done wrong when I did the reset?

I have an issue with a previously filed tax year where the US exchange rate was posted extremely wrong ($537.61USD = $3016.97CAD). Since it was not corrected when the filing was done, how do I now correct it? I am assuming I need to make an adjustment…
