Reconciled Transaction appearing on open periods being unaccounted by fix script from patch 9231279

Hello,

Applying the GDF script   'ap_multiple_pay_clr_mat_fix.sql' from patch 9231279 GDF FOR DUPLICATE PAYMENT CLEARING OR MATURITY EVENTS, always get the error in the 9231279_fix log:

The Following events cannot be Unaccounted On the same Date as the Original Event Date or the Sysdate because both Original and Current Periods are Closed

for a transaction for which the accounting date both GL and Ap periods are opened.

In the 9231279_diag log the same transaction appears on another period which is also open.

Any ideas how to unaccount this transaction  ?

Thank you
