Edit animations

Hi everyone,

It’s my very first time on this forum so I haven’t yet introduced myself
I’m a french developer, studying my last year in an engineer school.
I have used Unity by myself, helped by some teachers of mine.

I am actually trying to develop a RPG game alone and in my own rhythm, about to win points for my future career. I have succeeded in animating my character’s walk, but I want to change some movements. But I can’t edit my changes.

Could anyone please tell me what’s the procedure to make these changes? Is this a bug or have I missed a point?
I have attached an image showing the error and I will stay alert to give you all the informations you need, if you have the kindness to help me.

I want also to apologize about the English mistakes I could have made, I only speak it thanks to games, movies and the lessons I had, and you should know how poor our foreign lingual education is^^.

I thank you in advance and will be grateful to any kind of help

2.5d or 3d?

If you made the animations in a modeling program like blender, go back and correct inside that program.

I did the animation with the unity utility, on a copy of my main character (about not to break my scene). What is a 2.5d/3d? Thanks for the answers
