Hi based_kronberger, thanks for your contributions!

I noticed a couple things:
https://www.openstreetmap.org/way/175334415
here you did add the address to the building outline, but it was already present in the proper building relation: https://www.openstreetmap.org/relation/2342359

https://www.openstreetmap.org/way/1102636555
same here, you added the address to the outer way instead that to the relation, this edit also created a duplicated building

https://www.openstreetmap.org/way/369730250
here you duplicated the address to a building:part. You also added the tag building, but an element can't be a part of a building and a building at the same time

here you changed addr:street from "Sheshi Skënderbej" to "Rruga Sheshi Skenderbej", but there's no element with such name in the database as far as I know
you also changed building=office to building=yes. Usually a value should changed from a generic one to a more specific one, not the opposite.
