I was correct in my reply in the other topic you posted recently. This is cause of Greater London has nested cities within it. When that occurs, streets will be listed twice in an activity page; once for Greater London & once for the smaller city/borough (ex: London Borough of Haringey).
Looking at your most recent run (here), it reports 11 streets completed & 33 progressed on that run. On the Completed tab, you’ll see Avondale Road listed and underneath it it will specify the city that street is in (Haringey). You can select the Go button and it will zoom to show you all the nodes for that street. If you return and go to the Progressed tab, you’ll also see Avondale Road but instead it will list Greater London under it. If you select Go next to that one, again it will zoom but this time it will show that there are multiple different Avondale Roads in Greater London. In order to mark the Avondale Road for Greater London complete, you would have to run all these separate Avondale Roads.
