If she doesn't understand what you're asking, then either you're pushing her too fast, or you've not spent enough time helping her learn. It sounds to me like she's just not sure what you mean by all the different cues, and, like I said, I would go back and do more lateral work. Lateral work helps a LOT with making the horse more sensitive to the leg aid. Good luck!
