zsh auto completion of cp options doesn't list all of them

I've been working on setting my autocmp following this guide https://thevaluable.dev/zsh-install-configure-mouseless/ . I'm on a MacOS environment but for some reason when I try to autocomplete options it doesn't list the complete set of options. This is my config for autocomplete:

#Completion
autoload -Uz compinit
compinit
zmodload zsh/complist
#Amazing article https://thevaluable.dev/zsh-install-configure-mouseless/ 
zstyle ':completion:*' completer _extensions _complete _approximate
zstyle ':completion:*' menu select
zstyle ':completion:*' file-sort modification
zstyle ':completion:*:*:*:*:descriptions' format '%F{green}-- %d --%f'
zstyle ':completion:*' complete-options true
zstyle ':completion:*' matcher-list 'r:|=*' 'l:|=* r:|=*' #https://unix.stackexchange.com/a/259511 
zstyle ':completion:*' verbose yes
zstyle ':completion:*' group-name ''
zstyle ':completion:*' list-colors 'di=34:fi=31:no=33;00'
# zstyle ':completion:*' file-list all #Unfortunetly this messes up colouring
#Move with VIM keys Autocompletion
bindkey '^[[Z' reverse-menu-complete
bindkey -M menuselect 'h' vi-backward-char
bindkey -M menuselect 'k' vi-up-line-or-history
bindkey -M menuselect 'l' vi-forward-char
bindkey -M menuselect 'j' vi-down-line-or-history

When I try to autocomplete options for builtin shell commands I get the following:

❯ cp -
-- option --
-H  -- follow symlinks on the command line in recursive mode
-L  -- follow all symlinks in recursive mode
-P  -- do not follow symlinks in recursive mode (default)
-R  -- copy directories recursively
-X  -- don\'t copy extended attributes or resource forks
-a  -- archive mode, same as -RpP
-f  -- force overwriting existing file
-i  -- confirm before overwriting existing file
-n  -- don\'t overwrite existing file
-p  -- preserve timestamps, mode, owner, flags, ACLs, and extended attributes
-v  -- show file names as they are copied

I would expect to get the complete list of cp options as per the article. Is this possibly a MacOs issue for completion for zsh?
