i entered wrong transaction which disturbed my currency gain/loss

Hey all,

I had to enter a payment of in vendor account

The payment was 441,695.83 in local currency but i forgot to change the currency from USD to local currency and the amount posted in reporting is now 47,536,608.23. that messed up my currency gain and loss.

then i posted the right entry. 

I posted reverse entry for above mentioned entry, but my currency gain and loss is still there. even i reversed it with same exchange rate. but my currency gain/loss is still there
