Shouting at her isn't helping either. When you shout at her you're scaring her. Dog's don't understand most of our language. They really don't know that sit means sit. They just know that when we've trained them to sit. They either recognize the hand signal or the word that is given when their bum touches the floor.
When you catch her in the act firmly(not shouting) tell her "no". Use a low, deep tone of voice. Like a man's voice.
ETA: I just read you have a crate. Do you have mental stimuli toys or teething toys?
Moving crate may just make her more uncomfortable.
Be STRONG. Don't listen to her. Put some headphones on and blast some music to your ears. Do not give in! I know it's hard to not give in during the beginning. But it is for the best.
