I didn't struggle too much with this one, but I found pretty quickly that when I was goofing up, I was using the L-stick, like any normal person would think to do. Because I was sometimes overpowering my moves and moving over too far when I really just wanted to move one column over.
So, I figured that using the left D-pad (+) was way less sensitive and once I started using it I was able to pop this in a cinch.
Good luck!
