Hello! Thank you for the updates. It seems your changeset crosses many countries. Please retain your changeset smaller. Let reviewers and other mappers could check your edit easier.  it's impossible (almost) to keep track of the database and changes if changes in huge areas.
So I kindly ask you when you edit, retain your changeset in a particular smaller area -such as countries/provinces/municipality- save it first and then move to another area. Examples:
you are adding/modifying 10 objects in 2 distant cities => make 2 changesets, 1 per city.
you are adding/modifying 5 objects in 5 countries => make 5 changesets, 1 per country.
You'll find more information on the reason in this article: https://wiki.openstreetmap.org/wiki/Changeset#Geographical_size_of_changesets
