Cannot see my selected options in Finder sidebar
I am not sure when it happened, but all of my options are missing from my Finder window sidebar. I never turned them off (as far as I know), and when I indicate in Finder Preferences which items I would like to see listed, the changes do not take effect. Please see attached. What am I missing? Thank you in advance.
