Changing staff size on only certain systems

Hello everyone,

I’m super confused about this. As far as I’ve researched on this forum it should just be as easy as changing it down in the properities panel while in engrave mode but this has no effect. I have one page of music that is just a touch too large and I want to shrink it down without having to shrink down my whole document! Let me know what I’m doing wrong here.

You select the later System Break from which you want to keep the original staff size. Go to the property panel and toggle the staff size button.
Then go to a prior System Break, do the same and change the staff size slightly.

This doesn’t work for me, unfortunately.

Wait, is it under SPACE size?

Yes, that’s the term.

btw., you can do a similar procedure by applying local Note Spacing changes.
