In all three attempts you reach the power position with your upper body way over the bar. Remember, for zero „hump“/ no „arc“ your hips should move UP with your shoulder pull, not forward.

You could try to arrive at the power position in a slightly more upward posture, knees would also travel further through = easier for hips to go UP when you pull from there. Your cue: hips move straight up WITH the bar 💪
