Dynamics colliding with notes

I have a layout with 18 staves on it. Nothing crazy, it’s pretty typical of any score that you might buy.

But, it’s kinda crowded, especially dynamics between parts. I’m new to Dorico (can you tell?), and know that part of the philosophy is that either it will “do the right thing” or if that’s not good enough you can configure it better. I’m not sure why it’s displaying like this… I’ve set the page size to Concert, but even then I’m not sure why it matters. I’m coming from Sibelius, where adding an instrument will trigger a “do you want to resize things to make them fit” prompt. I figure Dorico can do something similar. I’m just not sure how.

(if anyone knows how to display an image that I’ve attached, I’d love to learn how to do that as well)

Dorico won’t change the size of the paper (or the staves) unless you tell it to. Layout Options > Page Setup is your friend.
