Leader doesn't have textures, icons, background. Only fallback appears

[nuclear_ghandi]

Hello, I'm trying to make my first mod and faced with problem. I have working leader (I can choose him and start the game).

But there are no textures, except fallbacks. I've checked XLPs and re-added textures using MC's guide (using the AssetsManager). So, I really can't understand where is the problem. Everything is perfect in the code :<

Hope for your help, guys
