Display settings keep reverting to mirrored displays (XFCE 4.20.3)

xfce-display-settings set my display layout with "Mirror displays" turned on and won't let me turn it off. It just reverts back to being on when I hit "Apply". I used to have them extended before updating my system.

I've tried deleting my ~/.config/xfce and ~/.cache/xfce which temporarily set it to extended (though in the wrong order) until trying to change my display settings again, where it set back to mirrored.
