Why doesn't vim use the theme I specified in the settings?

Question

vim

I installed this monkai
color scheme using Vundle.
I registered the settings in .vimrc

"colorscheme
set background=dark
"set termguicolors
colorscheme material-monokai
let g:materialmonokai_italic=1
let g:materialmonokai_custom_lint_indicators=0

If I type colorscheme and ctrl+d on the command line, then material-monokay appears.
The problem is that if I exit .vimrc and go again, the default theme is set and says that material-monokay was not found.
Why can't vim see the color scheme?
And in other things, here is my entire .vimrc

set nocompatible
set backspace=indent,eol,start
set history=500
set ruler
set incsearch
set clipboard=unnamedplus
set nu
set hidden
set termencoding=utf-8
set updatetime=0
set wrap
set showmatch
set hlsearch
set tabstop=2			 " To match the sample file
set shiftwidth=2
set noexpandtab		 " Use tabs, not spaces
%retab!						 " Retabulate the whole file
set wildmenu
set wildmode=full
map :call amv#toggle_spell()
imap { {}O
imap [ []
imap ( ()

if &t_Co > 2 || has("gui_running")
    syntax on
    set hlsearch
endif
set t_Co=256

" Configure 256 colors for xterm mode
if &term =~ "xterm"
  let &t_Co=256
endif

Answer 1

After a lot of fiddling, I found a solution.
You need to copy the material-monokay.vim file from bundle -> theme name to .vim/colors
This helped
