Dorico pushes a staff to a new page

Hi there, on all my pages I fit 5 staves of piano music very easily, but Dorico (on one of the pages) has decided to push the last system onto a new page without me asking it to! There’s plenty of room on the prior page for it, is there a way to bounce it back over? Cheers.

Sure. Search the online manual for “Make into Frame,” which is the function you’re looking for.
