Aligning measure numbers vertically

I enabled the option to put boxed measure numbers at the top and bottom of my orchestral score. However, they don’t line up vertically. See screenshot – they jump up and down according to the contents of the lowest stave, creating a very messy look visually. How can I align them all?

Layout Options > Bar Numbers > Placement > Align bar numbers across width of system.


Ahhh perfect. Thank you!
