CoC: Diagnostic window takes over screen - coc.nvim

Question

I am setting up neovim, with CoC.
It seems to work well, but with one big problem: My diagnostic windows are very large
I am not sure why this is. I would expect this to be only a few lines. Ideally, it should show up somewhere not directly over the code, but I'm not sure how to configure this.
This is my neovim config:
call plug#begin('~/.config/nvim/autoload')
Plug 'easymotion/vim-easymotion' " Get to where you want to go fast
Plug 'nanotech/jellybeans.vim' " Pretty theme
Plug 'scrooloose/nerdtree'
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim' " Fuzzy search
Plug 'jiangmiao/auto-pairs', { 'tag': 'v2.0.0' } " auto-pairs of parens
Plug 'Olical/conjure', {'tag': 'v4.15.0'} " Interactive Clojure Eval
Plug 'guns/vim-sexp' " paredi for vim
Plug 'tpope/vim-sexp-mappings-for-regular-people'
Plug 'clojure-vim/clojure.vim'
Plug 'neoclide/coc.nvim', {'branch': 'release'} " Language servers for vim!
Plug 'w0rp/ale' " linter -- TODO: maybe lsp obviates the need for this?
call plug#end()

Help would be much appreciated. Mainky:
Why is the diagnostic window full-screen?
Is there a way I could configure this to be smaller, or to show up somewhere else? (perhaps below the main pane)

Answer 1

Problem was
" Auto adjust window sizes when they become current {{{2
set winwidth=84
set winheight=5
set winminheight=5
set winheight=999
" }}} End section
Removing this did the trick
