...now only if we could get rid of the glove swim.
DD is dealing with this as well. Used to resemble Superman in flight after releasing the ball. We just focused on "glove in front" or "glove up, glove down." IMO it's a good idea for some of these things to work without a ball to help muscle memory - just focus on technique. Do hundreds of reps...glove up, glove down. Then when you re-introduce a ball, do the pitches at a very, very slow speed which focuses on good mechanics. The muscle memory eventually sets in!
The upside to all of this is that there will be a velocity and accurace improvement as a result. A key to fixing the swim is to get the arm and hips in good sequence together...my little "swimmer" has struggled in this regard a bit. With the swim the hips were closed to the plate THEN the arm was coming through, and her "miss spot" was thus to the right side (from the pitcher's view) of the plate. With better timing this doesn't happen but when the body first explores these new mechanics the arm might fire the ball to the left as the timing gets better - then it's just an adjustment back.
