invalid column pattern error

[rudrab]

Hi, while opening any csv file, I am getting error:
Invalid column pattern

I have installed the plugin using vim-plug and used:

" CSV: {{{2
if exists("did_load_csvfiletype")
  finish
endif
let did_load_csvfiletype=1

augroup filetypedetect
  au! BufRead,BufNewFile *.csv,*.dat  setfiletype csv
augroup END
" }}}2

no other csv related config is there in my .vimrc.
A sample csv is also attached.
head.csv

This file when opened in vim with ignoring the error is coming as

I would like to get rid of that error and want it to be properly columned.
