At the moment they appear greyed out, but this is confusing if there are a lot of labels, they go off the screen. Only the labels present should appear.
I think there should be an option to enable/disable the display of only the present-in-sentence labels OR there should be search box (with autocomplete) for finding the non-present labels.
