You should be able to unselect this wrapper object like this:
This will give you the list without the empty object.
Okay, this IS NOT an answer. The forum page won’t let me drag/drop pictures in the comment section so I’m putting them here. Ugh^ugh.
You create an object of entity ESNCatalog for the root. The root is an array, so it exists, and therefore you create an (empty) object for it.
You can create a new entity to map the root to, so at least it won't show up in your grid. You can also delete this object after the import, so your database remains clean.
Too easy, thank you!
