Possibly because we mark site_slug as optional here:

/${ langParam }/plugins/scheduled-updates/:site_slug?

	if ( isEnabled( 'plugins/multisite-scheduled-updates' ) ) {
		router(
			[
				`/${ langParam }/plugins/scheduled-updates`,
				`/${ langParam }/plugins/scheduled-updates/:action(create)`,
				`/${ langParam }/plugins/scheduled-updates/:action(edit)/:id`,
			],
			redirectLoggedOut,
			navigation,
			scheduledUpdatesMultisite,
			makeLayout,
			clientRender
		);
	}

	router(
		[
			`/${ langParam }/plugins/scheduled-updates/:site_slug?`,
			`/${ langParam }/plugins/scheduled-updates/:action/:site_slug?`,
			`/${ langParam }/plugins/scheduled-updates/:action/:site_slug?/:schedule_id`,

Checking to see if it goes away and nothing breaks when making at mandatory.

Still happens when a required site_slug
