How to reset this huge empty space?

Doing a couple of “ends voice” commands increased the space between two staves. How to reset this?

Ok, found the solution. I changed the space size in setup and rechanged it to what it was before. This corrected the problem, but still, this is a bug that should be looked at!

I’ve experienced this too. I found if I saved the project, closed Dorico and reopened the project, sanity was restored!
