Hello and welcome to OSM.

It is advised to *not* upload edits made on distant locations at the same time.

You want to edit buildings in England and in Australia? Fine, but please finish your edits for one country, and *then* upload them to the database. And only when this is done, start editing the other place.

One upload = one changeset = one bounding box in OSM. The size of that bounding box is determined by the min/max longitude and latitude of the objects in it.

The edit you uploaded right now spans over a huge territory, covering about half of the planet. This is unnecessarily annoying to mappers reviewing changes in their own country.

Have a nice day.
