IMO This is simply a timing issue plain and simple. She is getting beat to the spot. What happen when you get beat to you spot as a hitter? You rush. Just need to get the forward move happening at or just before release.
Red dot is the ball right at release, she hasn't even begun to start her sequence in this fram

Ball already on her, in this frame she just then got to heel plant and started to launch.
