Wenns denn überhaupt eine Relation sein muss. Es sind ja offensichtlich einzelne Wände.
Der Wert des name-tags entspricht m.E. auch nicht den Anforderungen an Eigennamen osm.wiki/DE:Namen#name_ist_nur_der_Name

relation/16062825 ist kein Multipolygon. Multipolygon-Relationen dienen der Darstellung von Grundflächen und haben lediglich geschlossene Umrisse von Einzelflächen als Mitglieder.

Before you delete elements, please make sure that they have no function, e.g. as a member of a relation. Otherwise you may destroy regular objects:

Do NOT delete objects and then map them again! You will destroy the chronology of the objects and the work of your fellow mappers.
Do NOT tag objects as something they are not. For example wooded areas as buildings.

Please remove fake buildings and fix geometry issues

If you mean the area enclosed by http://overpass-turbo.eu/s/1v4W : It neither had a connection to the heath area nor was it defined as such.

A water area, intermittent or not, is not a heath area. That is why it should be exluded as inner member.

Der war Bestandteil des Multipolygons http://overpass-turbo.eu/s/1v2a und ist ein Überbleibsel der Löschung der Relation in changeset/130988625 (https://osm.mapki.com/history/relation/1926938)

Anscheinend war die Antwort doch nicht ohne Sinn, denn offensichtlich hast Du dich mit meinen vorherigen Hinweisen befasst und das unsinnige und dazu falsche Multipolygon wieder gelöscht und das residential-Multipolygon angepasst.

Da musst halt schauen, ob sich andere landuses innerhalb eines landuses befinden und nicht Bestandteil eines Multipolygons sind oder ob sie andere landuses überschneiden. Und das am Besten bei Erstellung der Flächen und nicht nachträglich.

Und dieses neue Multipolygon ist völlig ohne Sinn: relation/15823200

Berichtigung:
Außerdem gibts noch einige überlappende landuses z.B. way/991982907 über way/30925605.

relation/15818189 ist kein Multipolygon sondern ein einfaches Polygon (sprich way). Multipoyone dürfen auch kein Mitglied eines weiteren Multipolygons sein (relation/15818190).
Aßerdem gigts noch einige überlappende landuses z.B. way/99198290 über way/30925605.
