Hi
Images cannot be linked to a project. If you specify a value target e.g. dataset Id = 5, the image will be imported in the dataset with id 5. The savedProject target was used by the deprecated Importer client to store preferences i.e. display the previously selected project/dataset the next time you log in, but it is not taken into account during the import process.
Those field should be removed to avoid confusion.
