If you have exploded and object, there is unfortunately no way to un-explode it (unless it was the last thing you did - then 'undo').
You would have to delete and put back the origin object.
If you want to get rid of the hotspots, then select the hotspot tool in the tool bar and then press CTRL+A.
This will select all of the hotspots in that elevation.
If you are happy with that selection you can just delete them.
If there are other hotspots that you would like to keep, then you will have to de-select those before deleting.
