Hi. Is there a way to remove deleted marketplace listings from my product reports? I was learning the inventory manager, and created a couple test listings that are now deleted. I generated the reports before deleting them, and they were in the reports. After deleting them, they are still in the reports! Is there a way to remove them form my reports? Does anyone know if they will eventually disappear after a certain amount of time? The deleted test listings also appear in the list when I try searching for related items/products when editing my listings, which seems weird! I would have at leat renamed them to "Test Item" before I removed them if I knew they would seem to be in my reports forever after being deleted. Can anyone help me with this or does anyone have a similiar situation or have any advice for me? Thanks!
