Condensing quandry

Any idea why these clarinets are suddenly not condensing? Everything looks fine to me.

Is it because there’s an instrument change to B-flat clarinets mid-system?

I’d have to see the project to be of any help. You’re welcome to send it privately if you like.

I can DM it to you.

I went to Layout Options > Players > Condensing and activated Allow instrument changes on condensed staves.

It seemed to do the trick? I didn’t check for any effects it had on other parts of the layout though.
