How to delete old items from marketplace?

[Arielle Simondsen]

When marketplace changed over to the latest viewer managed, I had unassociated all my no copy items and gotten rid of my magic box etc.

Now, however, I still have a bunch of old listings that have no associated items that are listed in a section above the viewer-managed marketplace listings. they are all unlisted but I cannot delete them or get rid of them and I really just want to delete them once and for all. Im tired of having to scroll past them all to get to the proper active listings.

Does anyone know how? thanks!
