Hi BUDO NDONBI MATHIAS,
your recent edits have left behind several errors regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=0.22706&lat=9.64418&zoom=13&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

https://overpass-api.de/achavi/?changeset=147016630

This kind of error irritates routing software and looks ugly on the maps.
Can you please fix this?
Kind regards
Guido
