N and S (Normal & Small font)

In An Affair To Remember there are the letters 'N' and 'S' displayed in red over some of the bars. This is in the web editor. I'm at a loss as to what they mean and wondered if someone would clue me in. I also wondered how they are added and deleted. Thanks.

This is the size of the chords (Normal and Small.) Usually we use Normal, but if space is limited, then Small. The red indications (there are others) are not displayed in Song view, just when editing. To cancel, click that beat, click the X in the Chord size box.
