For some reason, you added a layer=1 tag to part of Chichester Mews. If you don't know what a tag means, as is obviously the case here, don't add it. You also dragged part of Chichester Mews onto the corner of a house on Thurlby Road. Repaired in https://www.openstreetmap.org/changeset/150382725

You have also added badly traced houses on Broxholm Road and Glennie Road. Drawing terraced houses as if they were rather wonky detached houses is of questionable utility, but I have left these untouched. Someone else will eventually have to waste their time re-drawing them.
