There is a checkbox on the Template component called “Do not run Template on each row”. If you check this, the Template will only run once.

This is because you do not have Conditions on your Model to limit the number of records returned — your Field Editor is showing itself for every record in its associated Model. If you only are expecting one record to show up in your Field Editor, you will need to add Conditions on your Model.
