Seems those regions are not offlined(unassigned) explicitly from their serving regionservers, can you restart HBase or those regionservers and check again?

It sounds not a clean and recommended way to remove data/region like this, why not just delete the table? Or you just can be sure the old data are confined to some regions? If this is the case, you can first un-assign these regions before your below two steps.
