Trial Balance Mismatch

We are in 11i and using MRC.  In our Pesos SOB we ran both trial balance in Peso  and in US Dollar.  We  copy this data in the our US Dollar Reporting set of book. However, when we run the Trial balance is the reporting SOB it does not match with the trail balance in Peso Set of book in US Dollar.

We noticed that the mismatch is mostly in the accrual account.  We believe it should tie,  I would appreciate if you can give us some direction as the reason for the mismatch and  the approach to fix it.
