Bank Reconciliation

Bank Reconciliation

Hi I have been using Zoho books I am however experiencing difficulties while doing my bank reconciliations. 

In a scenario where we have inter bank transfers from a USD bank account to a KES bank account.
I am getting a difference in the two transfers while doing my bank reconciliation.

I have tried to change the exchange rate so that the two balances reconcile but I am still getting a difference that i can not attribute to any particular account.

Kindly advise
