According to your log, you have a tvshow.nfo file (containing xml) in the Once Upon a Time (2011), but it doesn't have an <episodeguide> tag in it. All your episodes are being enumerated correctly, but without the episodeguide URL, there's nothing to match them against.
Delete the tvshow.nfo and everything should work.
