Am I doing something wrong?

[eggswift]

your animation duration

[zyflovelam]

What should I do now? I have been removed the animation when the item deselected. and another thing happened, same as this thing, I tapped items quickly, 'Free Books' first, and then 'Community', and now, 'Free Books' still highlight, and 'Community' still unselect like before. and also, the 'Community Controller' displayed.

Could you help me, please?
