Some of SWMH's namings are applied via the landed_titles file rather than localisation, so there's sadly no decent way to override it.I installed without SWMH localized titles in the installer and yet several titles are named in nativa languages like England, Angliettere and Scotland Alba. Also William the Conqueror scenario is the first one and should probably be the third instead?
As to the bookmarks, that's a Project Balance thing. That bookmark is the primary balancing point, so it is placed first.
