Delgado was crated at night until he was 2 years old, he would get bored if left out overnight as well and either wander and whine or chew something he wasn't supposed to. It can take time before they outgrow it, it's easy to redirect when you are awake but when you're asleep that's a whole other kettle of fish.
You could try keeping her in your room, a babygate across the door or close the door. That way if she does get restless or destructive you should hear it and you can redirect her to her bed
