Street appears twice with different street names

Green Dene Green Dene - CityStrides
Combe Lane (the northernmost bit) Combe Lane - CityStrides

appear to the same road.

Before the latest CS import I had renamed the “incorrect” bit of Combe Lane to Green Dene but it seems CS is now picking up both.

I checked OSM and as far as I can see my edit to Green Dene is still the one in use.
