Normally I wouldn't reply to my own post, but I've solved my problem. The solution is not an obvious one, so here goes.
Up in the left hand corner of the Spotify app window you'll see your own name, click it.
Select "profile" from the drop down menu.
The profile tab will load to "Overview" and within that you can scroll down to the "Public Playlists" section.
All I had to do was click the title of my "Starred "list and all of a sudden all of my lists appeared over to the left where they always had been before.
It seems silly that this simple, yet not at all obvious process, solved a problem that was causing me such angst. Hope it helps anyone else having the problem!
