Reports; Saved Settings; Editing gives "Failed to create Report." error when moving to Data Export Settings page and settings cannot be saved

When editing Saved Report Settings for a report based on a data-entry form such as Bank Entry List, moving past the "Printer Settings" page to the "Data Export Settings" page gave the following error:

Failed to create Report.

Report must be created with an 'ExternalObject1' parameter of type finBatchBank.

This prevented the settings from being saved.

Since this type of Report is not exportable, the "Use Data Export Settings" checkbox is now disabled and the export settings hidden.
