Makes more sense. Didn't realize you were talking about the note itself and
not the reference in the text. Click ¶ on the standard toolbar to turn on
nonprinting characters to see if anything is awry--you should have a grey
arrow for the tab and a grey ¶ at the end of the note and plain grey dots
between the words. I wonder if somehow you could be getting non-breaking
spaces (grey degree symbol).

Failing that, with the cursor in a misbehaving word, click on Format | Style
and see if there is anything odd about the style definition.
