You are correct, and Sylvan was already represented as a residential area:
way/674175738
I left a comment on the changeset that created the node, if it isn't deleted in a few days I will do it myself.

This should also be deleted, because the Sylvan residential area is already on the map.

UHS is already on the map. You should delete the node that you added.
osm.wiki/One_feature,_one_OSM_element

You set building:levels to 12, I'm guessing it was a typo.

I fixed this already btw

Please be careful and review what changes are being made before you upload them, you accidentally made a driveway a couple miles long

I don't think there is any reason to add a node for Frank because it is already on the map. I would recommend deleting the node you added. If you wanted you could add the short name tag to the building and write Frank there too.

The same goes for your other edit adding the Townhouses as a node, because the residential area is already on the map.
