NinjaTrader is designed to only show active/working orders on the order entry windows, so since the stop and target order of an ATM are not yet live orders, these orders are excluded from the display. Once they are submitted to your broker, the orders appear and can be managed. The only alternative would be to manually place the stop and target order as an OCO pair, but this runs the risk of one of these orders filling before your entry order fills.
Please let me know if I may assist further.
