I'm very glad they're working to make you more confident in your jerk. You have the bar in the right place overhead, it's just a matter of getting your footwork down. From the looks of the last training session, it looks like you're on track.
Keep on doing them -- the problem won't be fixed in a day or week, but with consistent focus on correcting your movement, you'll be good in "no time."
All the best,
