Not able to edit Allow Accounting on Manage Invoice Holds and Release

Hi All,

Our requirement is to not allow Accounting to happen if the Invoice is on Hold. So we went to " Manage Invoice Holds and Release " and Uncheck the Allow Accounting on all the Holds . We were able to Uncheck for all the Holds except below one as the Allow Acccounting field is greyed out and not letting us to update. Please note there are other predefined holds which we are able to edit but not for the below once. Could you let us know why its is not allowing to edit it.

List of Holds where Allow Accounting is not editable.
