Joining/leaving  Meadow Road itself nearer Holmes Bridge as ntzm suggests agrees with Sustrans and was suggested by https://dent.org.uk/sustrans/sustrans-ncn-inconsistences/

Many other inconsistencies suggested near Derby are due to Sustrans data errors (or improvements not yet signed on the ground https://www.openstreetmap.org/note/3575289 ) but for Meadow Road it might be OSM that needs to be updated.
