Problem in import sprite

Hi. I have a sprite like this.

when I want to Import it, construct asks me about rows and columns and I write 8 by 8.

after the sprite is imported, each frame has a different shape. why and how can I fix it?

actually, frame 1 to 19 are in idle mode but they move right.

thank you.
