I have all creases but Crane mesh is not forming right

Hello,
In my file you will see that I gave all input of boundry, mountain and valley folds. Although Cmesh is formed, I can’t fold it. I tried my best to identify the problem but couldn’t. Help please… I can’t think of any solutions.
By the way this pattern really folds, I checked it in Rigid Origami Simulator.

Thank you
