Hi there and welcome to OSM!
Please review this change, it seems that you have changed the existing highway tags instead of adding a name tag.

Hi there!
I changed highway=yes + living_street=yes
to highway=living_street.
See highway=living_street

Alles klar, so hatte ich mir das auch erklärt.
Änderst Du es bitte noch ?

Hi there!
Please check the tag lanes=-2
Did you mean layer=-2 or lanes=2 ?
way/123664270
Same problem here:
way/123663710
way/123664139
way/123664263

Hallo!
Wiese setzt Du lanes=1;1 für z.B. diese Straße?
way/37118597
Meine Zählung ergibt lanes=4, jeweils 2 in beide Richtungen.

I am not a local. I noticed this changeset because of the strange attributes.

Hi there!
I've changed highway="Station Roundabout"
to highway=mini_roundabout:
changeset/35904056
Is that OK? (I am not a local)

Hi there!
The tag highway=plaza was only used here, and if I got that right, there is really no way to walk around the garden on this way.
So I think landuse=plaza is enough.
See my changes
changeset/35902532

Hi there!
You have created a lot of nodes which seem to be highway=bus_stop here,
but you stopped somehow.
See highway=bus_stop

Hi there!
I wonder what natural=Zai means.
Is it a typo?
way/383935014
way/383934981

Pardon, habe den Link vergessen:
way/385344323

Hallo!
Ich frage mich, warum Du manche Wälder als landuse=forest erfasst und einen als natural="managed forest".
Ist das Absicht oder ein Wurm in Potlatch?

Hi there!
What is meant with highway=Maradagahadeniya ?
Was it a typo?
way/377571218

Hi there!
Please check : I've changed the typo highway=trea to traffic_signals:
node/452354569

Hi there!
Please can you explain what you wanted to map with this way:
way/191888547

OK, I've changed them to disused:highway.
If I got you right the new cycleways will probably not be in the same place?

Sorry, forgot the link to the way:
way/286236733

Hi there!
Please, can you explain why you need a highway=water ? If I got that right, you added this way to calm down OSM inspector? That looks not like a good idea to me.

I see. You can use lanes=1 for this
or width=* or both. OK?

Hi there!
highway=x-cycleway is rarely used.
Are these ways closed (disused) now?
See e.g.
way/32132176
