Vim plugin for csv files

Hi, 

  When I open up CSV files with vim, I get an error message:

CSV Syntax:Invalid column pattern, using default pattern \%([^,]*,\|$\)

CSV Syntax:Or ftplugin hasn't been sourced before the syntax script

But I don't see any plugins in my vimrc that could be causing this. How do I see what plugin is opening the csv file and open it using the raw format (or if possible, fix the plugin)?

call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'preservim/nerdtree'
Plugin 'ctrlpvim/ctrlp.vim'
Plugin 'airblade/vim-gitgutter'
Plugin 'tpope/vim-surround'
Plugin 'tpope/vim-fugitive'
Plugin 'sheerun/vim-polyglot'
Plugin 'cosminadrianpopescu/vim-sql-workbench'
Plugin 'unkiwii/vim-nerdtree-sync'
call vundle
