Hi Gisellakai,

Welcome to OpenStreetMap.
Please read our wiki before you start to work on the map.
osm.wiki/Main_Page
osm.wiki/Map_Features#Building

Various users have reported your wrong way of mapping.
E.g. a house should be mapped with building=yes not with barrier=wall.

Read the comments at your changesets:

I have blocked your account to get your attention for this problems so that you can fix the errors. I shall lift this block as soon as I get a reply from you.
