Some of the footprints you added here share nodes with highways: hold alt to prevent your cursor from snapping to exisitng data. You inappropriately tagged a building with a layer=1 tag (the one I flagged): generally instances of overlapping features should be resloved by modifying the geometry of features. Adding a layer tag suggests that the footprint is above the highway. It makes the warning go away but doesn't address the cause of the issue, warnings are there to grab your attention, then secide the best course of action sometimes ignoring warnings is the best thing to do. Please keep this feedback in mind when contributing in future. Thank you for your contribution. If you want to experience the OSM community or to get timely feedback from other mappers; I recommend that you attend a mapathon. You can find events here https://osmcal.org/
