Currency Reval

Hi, Iam doing my year end and in the currency Reval account is saying that we have charges of €55,000. This is not correct but I dont know how to fix it. I have notices that Some SI where entered and there is a SC from currency reval against these invoices. The currency reval is very new to me, I would be to bothered but these SC are very large amounts, there was €25,000 on one invoice.  Also my USD bank account was giving a balance of $67.57 but the Euro side of that account was showing balance of €35,000. When I did foreign bank revaluation to clear this, it has debited exchange variance nominal showing it as a charge.   Can somebody please help me with this issue as I am not sure what to do and I dont want it affecting my profit and loss as they are not charges.

Thanks
