A common cause for the described behavior is when the server does not respond with the created data item (with assigned id field) to the create request. When the server does not respond with the created item, the dataSource does not add the newly created item to the pristine items collection. Which means that the dataSource treats the record as an unsaved item and when the user destroys it, the item is only deleted from the client side.
Could you please make sure that the create action responds with the saved to the database record?
