We'll have to keep working on this, but I'm sure she'll be a sitting expert soon
As you are just beginning teaching the behavior, you shouldn't be doing just the hand signal without treats yet. You move to that slowly, over time, as she excels at the behavior. If you move too fast with behaviors, they will disappear.
