Bug with biped texture [SOLVED]

So, my problem seem really strange : the biped model textures I've create aren't matching with the biped entity models. I've already see these topics : https://mcreator.net/comment/197934 and https://mcreator.net/forum/89084/please-just-give-me-texture-template-biped but I have done exactly what it was said and I've the same bug.

Did someone know how to resolve it ?
