After an Expense Report template set inactive, error to view DFF fields for the old Expense Report

Dear all

We set inactive date for an expense report template.

When users enquire the historial expense report with that inactive expense report template, the additional information (DFFs) failed to show on the report lines. See the screen captured.

Would you please adivse how to display those (DFF) fields on the enquiry screen ? since users may need to check the old records.

Thanks
