Hello wiemzayati ;
I noticed you added roads that are already drawing on OSM and they made the roads duplicated.
For example,
this is road
https://www.openstreetmap.org/way/1311281305
Identical and overlapped with
https://www.openstreetmap.org/way/1311361300
Also, you added floating roads
For example,
https://www.openstreetmap.org/way/1311288787
and I fixed some issues in changesets
https://www.openstreetmap.org/changeset/155782749
https://www.openstreetmap.org/changeset/155776006
https://www.openstreetmap.org/changeset/155739028
Could you please fix these issues?
Regards
