How can I get my Marketplace Listings Cleaned up to eliminate ancient No Copy items and some updated

How can I get my Marketplace Listings Cleaned up to eliminate ancient No Copy items and some updated items? I waited for the Marketplace updates. Thankfully I do not have a lot of items; but when I am trying to list new items; I have to scroll through blooming butterflys and old versions of products that have not existed for some time; and if you try to associate the wrong old product to a new one; it leaves a blank spot on the Marketplace Store Window for an associated item; but still shows it filling a spot when you are editing the item... I would really like to be able to clean out my Marketplace Inventory of Invalid Items. And please don't tell me to click the "Look For Errors Button".... It Found None... Thanks In Advance.. o,O
