Under certain conditions, the pasteboard configuration will differ from the default settings in the Preferences (Edit > Preferences > Layout).

This happens if you:

•Click the Fit pasteboard to page icon on the Layout toolbar.

•Enable the Center Page in the View preference.

This is handled by the Keep custom pasteboard settings when changing preferences check-box. Tick to enable it, and then, hold SHIFT pressed when clicking OK after changing something on the Layout tab, to apply the changes on the current layout.
