Hello.
In OSM, generally it's better to modify existing objects to their accurate state, rather than deleting them and create new ones.
In this changeset you deleted a building and instead drew 2 new ones. Doing this, you erased history of this previous object there and didn't transfer relevant tags to the new building.
Additionally, you added, apparently, recording studios, however you entered their floor numbers as their unit numbers. That is incorrect. OSM has a separate tag if an address has a floor number: https://wiki.openstreetmap.org/wiki/Key:addr:floor.
