Hi Esdras24,
your recent changesets have created a lot of errors regarding self intersecting lines and duplicate nodes:

https://tools.geofabrik.de/osmi/?view=geometry&lon=2.60655&lat=6.57336&zoom=13&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

Can you please fix this?

May be you like to reflect about how to map a building?

JOSM internal validator helps to prevent uploading such errors:
