Why is a frame on?

Amount of 3 frames my animation. (chest with lock)

follow me!

To open the lock using touch user begins, (lock-open>> jump anim to frame 2)
Now I open the trunk,
up with a swipe -> jump anim to frame 3, it works but stays on even opened the second frame, why?
I have to hide the images? But I believe so comfortable with it jump to frame anim.
