xdg-user-dirs-update not working with more than one directory

https://manpages.ubuntu.com/manpages/focal/man1/xdg-user-dirs-update.1.html Why is only the last directory being set in the xdg-user-dirs file? % xdg-user-dirs-update --dummy-output ~/test \ --set DOCUMENTS $HOME/Apples \ --set MUSIC $HOME/Bananas \ --set PICTURES $HOME/Oranges \ --set VIDEOS $HOME/Pears % cat ~/test # This file is written by xdg-user-dirs-update # If you want to change or add directories, just edit the line you're # interested in. All local changes will be retained on the next run. # Format is XDG_xxx_DIR="$HOME/yyy", where yyy is a shell-escaped # homedir-relative path, or XDG_xxx_DIR="/yyy", where /yyy is an # absolute path. No other format is supported. # XDG_VIDEOS_DIR="$HOME/Pears"
