Staff label alignment problem

Another question that probably has a really simple answer… some of my staff labels are aligning differently than others. My main issue is with the condensed horn and trombone lines, which I’ve included in screenshots below.

The trumpet 1/2 looks the way I’d like it, but the trombone 1/2 does not (horizontal vs. vertical). I also can’t figure out why the horn line says “hn.” twice. I think it might have something to do with a similar format issue in the uncondensed version- I’ve thrown a screenshot of that down below too.

Again, I’m sure this has a straightforward fix, but my googling has proved fruitless.

Your Horn 2 instrument has a line break at the end of the instrument name (admittedly this is hard to see in the Edit Instrument Names dialog, when the cursor is right on the edge of the text editing area and not obviously visible).

Be careful when editing instrument names: pressing Return doesn’t confirm the dialog, it inserts a line break.

If you go back in and either reset instrument names or position the cursor at the end of the text and press Delete a few times to make sure you’ve removed the line break, all should be well there.

Exactly what I needed, thanks Lillie!
