Both these options do NOT help resolve my issue. I'm already aware that I can make the items "Active" again to remove the "deleted" tag. However, this is tedious to do with large number of items and also messes up the inventory logistics - since I made them inactive because the item was out of stock and I wanted to remove the option of accidentally adding them in a future invoice. 

I am not sure why the "deleted" tag exists in the first place - what purpose does it fulfill? I can already see my Inactive items list under products/services. Even if it exists, why is it applied to PREVIOUS, ALREADY CLOSED invoices?
