ok, just tagging issues: the round feature is probably not a sports centre, and typically soccer is not played on a round pitch.
Can you describe what it actually is, and we find a proper tagging?

ok, just as said before, the grass is not natural=grassland

Fine, just don't use natural=grassland for urban greenery

Why did you delete the buildings you have just created?
In OSM we prefer to improve something that is not perfect yet, not to to delete and draw again.
So objects get a history.

in way/892583617, this is not natural grassland.
You can use landuse=grass and landcover=grass.

Which education level is the facility for?
Or, for what age of the students?

You were adding motorcycle parking.

If that is for more than one vehicle, please use
amenity=motorcycle_parking
If it has a roof, add
building=roof
or if it is a closed building,
building=yes

The capacity tag is for the numbers of vehicles the place holds.

This CS is fine, it creates new objects only.
However please give a meaningfull comment what you did, when uploading.
You were drawing building geometries, for which "knowledge" is not a sufficient source.
Please give the source you used, e.g. the aerial images.

Hi namprati,
it is fine to make your local edits.

For the older edits, a full rollback was necessary, since you had accidentally moved objects from Norway and worked further with them in Hanoi. However, these objects went missing in Norway.

Anyway, in your new edits there are again changes that affect the world. I will check them later.
