Revaluation leaving a penny when the months before the balance was 0

Summary: Currently we are revaluating the journals and the last known JE was booked to May period. There was no activity in June, July Aug for EUR currency and the revaluation process ran and revaluated to USD.

When you look at the EUR activity for the account in question - the net balance is 0.00 and the same is for USD - the net balance is zero.

But in August - there is a (0.01) net balance in USD for period activity.

Here is July- and the period activity nets to 0.00

Any idea as to why there is a -0.01 ?
