Animation running very slow

[Quamber]

Hi, i am developing the third level of my game for child education and using almost the same animations as i did in the first and the second level of the game but the animations are running very slow in third level to such an extent that i can count the steps of the animation.
The only difference between (first/second ) and third level is that the third level has increased number of images and that it has a countdown timer. Can anyone help me out in this issue?

Also that i am not starting a single animation sometimes i am starting even two animations
