Amanda, perhaps double-check that the relevant layout is selected on the left column in Layout Options. It may very well be that you’ve turned on multirests in a part or score layout that’s off the bottom end of the screenshot, but not the layout that’s actually in front of you.
That said, I’ve never seen what you’ve shown, where one page has multirests and the next doesn’t.
Is there any possibility you’ve got hidden stuff in the bars on the right hand page? Maybe turn on all signposts and double-check. Things like hidden time signatures are the usual suspects.
