Solved. The staves were too close (or the chord line was too high). Anyway, adjustments or either or both rectified my problem.

Mac OS 10.13.5, Finale 25.5.0.259 I can't enter chords manually anymore on the same document where I've entered chords before. Clicking on the note/beat produces no entry point.
