I did a test with your configurations on macOS, can't reproduce. And as you can see, the suggestions list is different from yours, there's no built-in suffix. What's your coc-texlab version? and the texlab version? I'm using 3.2.0

[krisfans]

my environment: wsl+ubuntu20.04+nvim 0.5.0+windows terminal+texlab 3.1. I just update texlab to v3.2, but this still exists.

Did you use a third party colorscheme ?

[fannheyward]

In your tests, the completion items all with built-in suffix?

[fannheyward]

third party colorscheme

Minimal vimrc, without color scheme setting.

[krisfans]

Seems to be yes

Minimal vimrc, without color scheme setting.

I set colorscheme gruvbox8 in vimrc

[fannheyward]

1. provides :CocList extensions and :CocList services
2. do you have any latex settings in your coc-settings.json?

I can't get built-in in the completion items.

[fannheyward]

And make a test without any colorscheme please.

[krisfans]

minimal.vim

if &compatible
    set nocompatible               " Be iMproved
endif
set runtimepath^=~/.cache/nvim/dein/repos/github.com/neoclide/coc.nvim_release
filetype plugin indent on
syntax enable
set background=dark
set termguicolors
" colorscheme gruvbox8

autocmd BufRead,BufNewFile *.tex set filetype=tex

set completeopt-=preview

    let g:coc_global_extensions =[
        \ 'coc-clangd',
        \ 'coc-texlab',
        \ ]

coc-settings.json

{
    "suggest.timeout": 500,
    "suggest.noselect": false,
    "suggest.detailField": "abbr"
 }

step

nvim -u minimal.vim test.tex

result

note

I found set "suggest.detailField": "abbr" in coc-settings.json is the key to reproducing the problem。 If the value of suggest.detailField defaults , built-in will disappear

[fannheyward]

"suggest.detailField": "abbr"

Got it.

Looks like it's a problem on WSL.

[chemzqm]

"suggest.detailField": "abbr" means set detail of LSP complete item to abbr of vim's complete item. It's expected.
