Hi Gazza.
I keep getting emails concerning double listings.
I have emailed support plus complained on the threads about not be always able to delete re-listed items from the sold section.
Had to go in and dellete a few doubles today.
I also get error when relisting, then 2 of the same items go live.
Its difficult with over 800 listings to keep track of what as gone on as a relist, what as not been relisted.
I also have the same trouble with my gallery.
Photo showing as not uploaded, then wham 2 to 5 of the same photo ends up in gallery.
