Thanks Peter, but yes, they are hotspots. I figured out somehow that when I try to delete them right after opening the file, I can select and delte them.
I deleted them from 2 elevations, and when I tried to delte them from 3rd elevation, they got locked again. So I saved, closed, and opened the file again, and continued to delete the hotspots from the 3rd and 4th elevations. When I got to building sections, they got locked again, so I repeated the above step and deleted all of them.
They are not coming back yet, so I guess that's that.
