FC Continues to open up TWO tabs in right pane

[prr]

FC insists on opening up two tabs in the folder pane. I went so far as to delete the one folder that was being opened (in addition to the one that I've told FC to open up). Now, it continues to open up that unwanted folder, but now I have to click an error message saying that the system cannot find the file path.

How can I get FC to only open up one folder in that right pane?
