Reproduce the warning through the Check Structure action and the Save as... flow using an arrow in Canvas, then trace the structure-loading and export entry points for the listed formats. Compare handling across arrow types and formats; done means no "Error at loading structure, wrong format found" warning appears in either scenario.
