Sorry, I've already tried your suggestions and they didn't work. I should have said that in the first place. I noticed this...bug, I guess, after I restarted my PC a few weeks ago. I tried rebooting, but that didn't do anything. By the way, if I have the Favorites highlighted/selected (while the libraries are disabled) and I enable the libraries, My PC becomes highlighted. I just thought that was odd. I also restarted the Windows Explorer process rather recently for a different reason, but the libraries issue is still...an issue.
