Vim command 0 goes to second column instead of first one

Question

When I press 0 in Normal mode, the cursor goes to the second column and not the first one. This is not the normal behavior stated in vim's :help 0.

I have tried disabling the remaps to move between wrapped lines from my config (below) and the behavior is the same. Is there any way to change this? Maybe a package it's interfering with the regular behavior but I cannot see which one.

Here is my .vimrc config file

set backspace=indent,eol,start " backspace over everything in insert mode
set nocompatible               " be improved, required
filetype off                   " required

" vim-plug manager
" Plugins will be downloaded under the specified directory.
call plug#begin('~/.vim/plugged')

Plug 'lervag/vimtex'
let g:tex_flavor='latex'
let g:vimtex_view_method='zathura'
let g:vimtex_quickfix_mode=0
set conceallevel=1
let g:tex_conceal='abdmg'

Plug 'sirver/ultisnips'
let g:UltiSnipsExpandTrigger = '<tab>'
let g:UltiSnipsJumpForwardTrigger = '<tab>'
let g:UltiSnipsJumpBackwardTrigger = '<s-tab>'

Plug 'itchyny/lightline.vim'

Plug 'sainnhe/gruvbox-material'

Plug 'scrooloose/nerdcommenter'

Result of map 0 :

  0           * g0<Space>

There is a space after g0, remove it should solve your problem.

Put this to your vimrc to show trailing space, tab and other stuffs:

scriptencoding utf-8
set list listchars=trail:┄,tab:†·,extends:>,precedes:<,nbsp:+
