Is she working on TTB?
Because, she is bringing the barrel back and down to vertically. The front elbow is pointing down to much.
Go the other way. Put the tee high and fairly deep rather than low and out front as in the video. With that new tee position and in slow motion how would she get to contact while keeping hands above the barrel. With her current swing thoughts, she won't be able to. That should help her think about how to fix it.
One good thought: elbows in set up will form a big 'V' facing downward. Swing should 'slam the V' toward the pitcher while keeping the distance between the elbows fairly constant. That's another way to get the front elbow to work up as Shawn is advocating.
