Hi,

It appears that this is an import of building footprints. Please note that if you did not individually review each building added in these changesets, this counts as an import and must be discussed and documented prior to uploading, see https://wiki.osm.org/Import/Guidelines

It also looks like each node part of the building ways are also tagged with 'building=yes'. These nodes shouldn't have any tags to comply with https://wiki.osm.org/One_feature,_one_OSM_element

I ask that you revert this changeset and follow the import guidelines/fix errors I pointed out before reimporting. If you're not sure how to revert changes, read https://wiki.osm.org/Change_rollback
