R12.1.3 AP and PO Reconciliation Report output displays FNDWRR Query String Parse Error

Run report in IMSI Payables Manager.  When report completes, view output and open. Report says completed normal however, output only says: Query String Parse Error

This problem is occurring on at least three reports:

1) AP and PO Reconciliation Report - click open, FNDWRR Query String Parse Error.

2) Miscellaneous Accrual Reconciliation Report - click open, FNDWRR Query String Parse Error.

3) Summary Accrual Reconciliation Report - click open, FNDWRR Query String Parse Error.

Any help is appreciated!
