File Sharing doesn't show main drive
Recently, file sharing from my Mac has stopped showing the main drive and only lists the external drives when connecting from another computer. I never changed my settings, this just happened on its own. I've tried turning sharing off and on and restarting the computer. It actually still works through Samba, I can see my home directory and the root directory. Maybe it's some corrupted preference file somewhere? I can't figure it out.
Does anyone have suggestions for fixing this? Am on the latest OS (10.13.1) on a Mac Pro desktop machine.
