When I build the geofabrik extract for Canada with the same options, the 'Where to -> Cities -> Spell Name' doesn't work.

For the map of Canada, the cities still show up in the list but they aren't found if you search for them. Removing --x-split-name-index fixes the problem. It's not a huge issue because I can just remove this option but I did want to report the problem to you.
