Relation: North Somerset (80277) | OpenStreetMap was incorrectly imported since it’s a county not a city. Many other places in England are in the same situation, which I’m slowly working to correct.
Based on feedback here in the forum as well as in private messaging, the smaller places are more correctly perceived as cities.
You use the phrasing “only some of the towns/villages within it” which makes me think there are gaps in coverage now. There is a new bug in the city update/creation process that can produce a city with zero streets … these cities will appear in lists e.g. in England, United Kingdom - CityStrides but won’t count towards progress until I fix them. I wonder if that’s the case (if you’re noticing gaps)…
