Sorry, I was insufficiently specific. On the right hand side of the properties panel there is a section called “Set local properties:”. If this is set to “Globally” then changes you make should affect all layouts. If this is set to “Locally” then changes you make to local properties will only affect that layout you’re working in.
You can also apply this retrospectively by selecting items and choosing Edit > Propagate Properties. This is mode-dependent, so Engrave-mode only properties don’t get copied if you propagate in Write mode.
