Hi Olayinka Omoboyede,
this changeset has create a huge amount of errors in the OSM database:

https://tools.geofabrik.de/osmi/?view=geometry&lon=3.38060&lat=6.70203&zoom=12&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=151110575

I have just reverted it to fix those issues.
