Sprite Rect Moves Between Frames

Hello! Long time reader, first time poster here.

I have a strange issue here where in a sprite's rect moves from one place to another when I select Walk01 vs Walk02. I will attach image to explain, but this causes the character to jump around during his walking animation. Also, the character I am using here is free on the Unity Asset Store and their name is Dragon Warrior, if you would like to try and reproduce the issue.
