Hello Tapa,
In all your recent changesets you've been adding blank areas instead of buildings. To change this, select an area in the editor then click on "Area" button in the top left and then search for "Building", this will then change the blank area into a generic building. Please note that untagged areas don't get rendered to the map but buildings do. You have also created a few overlapping areas in some places like here: https://www.openstreetmap.org/edit?editor=id&#map=20/2.6924346/-73.1903277
please fix this before continuing.

Kind regards,
Kits
