Adjust layout doesn't actually adjust margins?
Hello!
I'm trying to use the adjust layout feature to change a book's top and bottom margins. When I go to file>layout adjustment, these are the original settings:

This is what I change them to:

After the layout adjustment is complete, if I go file>document setup, I see the same settings I chose:

If I go layout>margins and columns, however, I see the original margins:

And when I measure the margins with a ruler, they're the original 1.125 instead of 1.
I've had a similar problem in other documents where I need to change the trim size. In file>layout adjustment, I'll change the page size and check "auto-adjust margins to page size changes." After the adjustment, same problem—the margins haven't changed.
Am I using the feature wrong? Is there a bug?
Thanks for your help!
