HI ManeraKai,
this changeset has created overlapping ways, the secondary street "Vukela Caddesi" is affected here:

https://tools.geofabrik.de/osmi/?view=routing&lon=29.09655&lat=40.95333&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

https://overpass-api.de/achavi/?changeset=145945685

This kind of error irritates routing software and looks ugly on the maps.

Can you please fix this?

Kind regards
Guido
