We have this resolved already and will be in next week's update. I'd just note for now that you're not missing because the animation is going slowly, the animation is playing out slow because your shot will have missed, so the impact here is entirely a visual one.
Batting needs a full range of shots, rather than just the bowling action, run, etc. so it's a significantly higher amount needed to add a style. There was a bit of rework done to the other styles though. Spin actions likely feel a lot less number wise as they are split between Off and Leg spin actions, while for pace all pace bowlers get all the actions.
Both are things still being worked on.
