Adding note is octave too high

I’ve building an part with the first stem. Now I’m adding the second stem of the notes (same voice). I’ve set Lock to duration and Chords. When I add a G it is adding one octave too high. How can I set the correct octave for all the notes I’m entering? (I can changing the note after adding with command-alt arrow down)

I think I read somewhere for chords you enter the lowest note first. Then it builds on that for subsequent notes. Someone will correct me if that is not correct, I am sure.

edit: Looks right. Hold ctl key to add notes below the existing notes.
