The issue is that you are only deleting the row in Kotlin/Java but not in your SQLite room DB. I guess you should be able to solve your problem by simply adding a line that deletes an address in your DB. here an example of how i would do this for your tvDelete clickable view:

val application = application as CustomApplication
    

viewHolder.tvDelete.setOnClickListener(View.OnClickListener { view ->
        mItemManger.removeShownLayouts(viewHolder.swipelayout)
        addresses.removeAt(position)

        //remember that in onBind you already saved the current Address as "fl"

        application.database.AddressDao().delete(fl)//here you delete from DB so its gone for good
        //notifyDataSetChanged() dont do this as it will reexecute onbindviewholder and skip a nice animation provided by android
        notifyItemRemoved(position)
        //notifyItemRemoved(position) execute only once
        notifyItemRangeChanged(position, addresses.size)//i dont think you will need this
        mItemManger.closeAllItems()
        Toast.makeText(
            view.context,
            "Deleted " + viewHolder.tv.getText().toString(),
            Toast.LENGTH_SHORT
        ).show()
    })

so i guess you were quite close already. please mind that i code in java so im not super confident all my code is correct but you get the idea.
